Monohydride Alcohol Classification (Part - 2) - Alcohol, Phenol & Ether, Chemistry, Class 12 Video Lecture

hello friends this video on alcohol
phenols and ethers part 2 is brought you
by exam feel calm no more fear from exam
sort of all these hydrate of hydrates we
have this cursed monohydrate by hydride
I had like the monohydrate are little
important because we have further
classification of monohydrate alcohols
it's based on the hybridization of the
carbon to which hydroxyl group is
attached example a toward right you know
although alcohol will have something
like this co h where OS will be attached
to one carbon so based on the
hybridization of this carbon we have
different types of monohydrate alcohols
so if this carbon is sp3-hybridized then
we have primary secondary and tertiary
alcohol or we have al I like alcohol and
been Joey calco will discuss about these
in the next few slight if this carbon is
sp2 hybridized carbon then we have
vinayak alcohol and fanouts
so we will discuss about if you see now
here in this definitions phenol is
nothing but a type of alcohol by so
there are two different definitions
actually in what accordingly one
definition the phenol is a type of
alcohol and the other one say is that
alcohol is only for anything and phenol
is called aromatic but you should not be
confused it doesn't matter right so
let's start with the primary secondary
enters through your core so as I told we
had discussed this primary means the
carbon which I am talking about is
attached to zero or one other carbon
secondary means the copper which I am
talking about this attached to two
colours
tertiary means three counts if you see
this is the carbon I'm talking about so
maybe this is the hydrogen here so I
they have two possible combination here
I let this C is three OS or ch3 ch2
so in both this case in this case this
carbon is a - 2 0 other carbon in the
case this carbonate is a task to one as
a cop right this is my stock album
great so long as the blue shark up in
stock oven is nothing but the carbon to
which awaits goodness - right this is my
primary alcohol
this is messing energy of God because
they are to our groups here in each of
this all group will have carbon here
also this tertiary you see correct this
is tache because this carbon attached to
three other carbons so we have discuss
this in the past few chapters are not
stressed on these and they are generally
liquid then we have a line link so Ally
li if you see here the stock of in which
I have this first draw the star carbon
here in the carbon which is attached to
each other start out with all these
stark of us in attached to a carbon that
is double bonds star carbon is not
double bonded
please note star cover is not double
burn starburns attached to a carbon that
is double bond if you see my this is my
star carbon that is sp3 hybridized if
you see and this carbon is attached to a
carbon that carbon is the double bond
that's called Li Li carbon if you see
this carbon is sp3 I can show you how
correctly in this car you see one two
three four points it is sp3 hybridized
this also you see one two three four one
sp3 hybridized
one two three four and these are also
generally liquid and hero so you see you
can further classify as one nearly Trudy
in your 3d you see these are the star
Carmen Lissa - - only one Carmen so this
is one degree this is the star carbon
this is a - do you want to carbon this
is 2 degree this is my star comment it
has 2 3 in the carbon - this 3d okay so
I can further classify allylic alcohols
into
1 degree 2 degree and 3 degree let's
start with been joining and that is also
sp3 so if you see this is my staff as to
which here this is my stock um and this
is my stock let me see this star carbon
is not part of benzene ring
so don't confuse this is not sp2 this is
SP 3 this is normal
alcohol and now if you see this star
carbon is attached to a benzene ring so
this is called benzylic alcohol right
where my star carbon is attached to
benzene ring or automatically
they also generates solids here also
getting classify first degree this
carbon attached to only one carbon this
is a carbon here one degree this carbon
is attached to one carbon to carbon this
two degree this cover and attached to
one two and three copies so you can
further classify the benzylic carbon
also
Manjari alcohol also has one degree 2
degree or 3 degree Oh God the next is
vanilla alcohol here it is sp2
hybridized in the star carbon itself is
double bonded so if we see this is my OS
bond this is my star carbon and if you
see this is double bonded so you saw in
allylic alcohol the star carbon is
attached to a double bond carbon the
star carbon itself was not double bonded
but in the vanillin alcohol the star
carbon itself is double bonded right so
if you see the O is born the star carbon
is double
and then a phenom so if you know if you
see the star carbon itself is part of
the means evening this is my star carbon
here the star carbon itself is part of
the painting correct these are not you
notes this might be known this is mine
you know and if you see here this is sp2
actually why it is sp3 sp2 hybridized
and the other one which we have just
discussed when I leak also sp2
hybridized I can show you why it is sp2
hybridized if you see this carbon here
there is one two and three C development
also you to count only once one two
three so sp2 this also point if you see
one two and three so it is sp2 correct
now we'll discuss ethers so ethers are
as a total form when the hydrogen is
replaced by alkoxy or RL oxy that is
over or o ER
so ethers are further classified as
simple or symmetrical ethers and mixed
or unsymmetrical ethers so in case of
simple or symmetrical ethers the alcohol
or the Riley loops attached are same for
example if you see c2h5oh c2h5 so this
part and this part is same or you can
have CH 3 OC s 3 so you see both part
are saying or you can have an on here
and then you can have it on air right so
they are symmetrical ethers because this
side this side is same and then you have
unsymmetrical ethers where these two
sites are not same for example c2h5oh
cs3 both are different or you can have a
fan on here then you can have CH 3 en
CBC this side and this side are not same
right say both sides are same it is
called symmetrical ethers if both sides
are not seeing it is called
unsymmetrical into them and they are
also generally liquid so let's stick one
numerical here and we know classify each
of these based on whether it is a a lile
angel of anion alcohols did you discuss
all these so you see this guy so this is
my star carbon and this star carbons
attached to a carbon that has double
bond so it is what I'll leave it on its
think this is either allelic or banana
think again which is this a violet or
Bonelli see the star carbon is not
double bond it is attached to a double
bond correct so one memory tip to
understand is this you know ally allies
means friends right so we have you see
the countries aligned like this the
countries has friends right so India is
friend with let's suppose China so idea
in China's are like so that way so if
you see here this is the star carbon and
this friend is a double bond right so
his his friend is rich right so here we
can the movie do you think of this star
carbon is not double gonna talk about
friend is double bond so Star Pawan
frame is a lie right and with that you
can see that it is a lying just a memory
to understand this start ominous not
dominant shark happens friend is
development rights taka one's friend is
double bonded so sort of unfriend Smith
friend means a lie
so it is highly alcohol same thing here
this is my star carbon start oven is not
double bonded to carbons friend is
double bond so it is also a lie like
this and this here also agrees my star
carbon because over shield is attached
to it and star carbon is not to burn but
stock ovens friend is double bonded
friend is a lie so it is also a lie Lee
correct now if you see this alcohol is
attached to only one carbon so it is one
degree this alpha that has to want to
carbon it is 2 degree this alcohol that
has 2 1 2 3 covered in this correct let
us see this this is my H group attached
to this carbon this is my startup right
so stock up on itself is double bonded
so it has to be vanilla alcohol if you
want to memory take for this stock our
it says double bond the stock oven is
the winner start upon his wiener so it
is banana car car
just please don't this was a lie league
because the stock oven was not dominant
acaba was not the winner taka burns
friend that is alive was the winners
with is a lie like a lock on here the
stock oven until is the winner so it is
banana car gone correct
this is my star carbon here in this
match are common the star governs part
of a romantic ring start oven is part of
Parramatta green straightaway - why not
stock up on is part of our wedding ring
it is fennel here this my stock up stock
oven is not part of her wedding ring but
stock carbon is attached to a benzene
ring right star carbon attached to a
benzene ring students benzylic this my
stock up stock up and attached to
benzene thing so it is also been very
stark our and this star carbon is
attached to a benzene rings but is also
in joining this star carbons attached to
only one carbon to it is for negative
injury this carbon is attached to one
two carbons it is to leamanczyk
this star carbon that has two one two
three carbon today's three degree binary
let's talk about these days this are it
is ethers both are same so it is
symmetrical inert these two are not same
so this um seven trigger correct this is
my symmetrical if it is unsymmetrical so
let us take one numerical easy numerical
very classified alcohol as prime music
into your tertiary this is my H this
master carbon stock of an attached to
one carbon only so it is one degree this
primary it's my star carbon stock
carbons friend is powerful so it is a
lie that is aligning but that is on the
question question is where there is one
degree or two really this covers a -
only one carbon through this morning
this is my star carbon attached to it
only attached only one carbon so it is
also one degree this is again my stamina
- 2 H and this is attached to one two
comma right wanted to come this also
carbon here this to me this is my star
carbon here sorry this is not so common
this is o H it is my star carbon and
this carbon is attached to one and two
carbon so it is truly
there is the way this is the way this is
my star carbon this top cover the - to
want to win three carbon today's three
just to repeat this carbons friend is
powerful friend is alive it is Li Li and
this is also this carbons friend is
powerful is Kalani
this carbon is Rick attached to benzene
so it is Ben's I lay here this carbon is
not a - to maintain so it is different
