Chemical Properties of Carbon Family Video Lecture - NEET

hello friends this video on Ibaka limits
party walking by exam fee a.com no more
for you from exam let's talk about some
chemical property change what the reacts
with air hydrides reaction with water
halides let's start with the reaction
air see the first property is all the
members when he talks in my oxides
monocytes and I except example carbon
then in heat with limited oxygen less
oxygen it from Cameroon aside heat
carbon with ample oxygen pilgrim power
dies so it from Oxford one of sites and
diopside - oxides in the higher
oxidation state are jelly more acid so
this one if you see it has last two and
this is plus four this guy is more
actually the dioxides if you see are
more acetic acid if you see some more
ascetics and these guys are important so
you see these guys are acidic dioxides
these guys are improperly why because
you see these are metals and non metals
and metalloids so they have acidic oxide
and I have said these days are metal so
they have amphoteric our basic our cells
right that's the reason that these are
metals and metalloids lammeter's and
metalloids so they have acidic oxides
these guys are made let the end in so
they have amphoteric on basic so you see
ascended to NP po2 they are and what
recognition it does if you see if you go
down the group the basic nature increase
missing nature of oxides oxides this is
similar to the trend we have seen in the
boron family and if you see among more
oxides if you see co is neutral GE o is
acid a and these are so if you see the
carbon monoxide is the only exception
here it is neutral why why it is neutral
it has to be based acidic right when
the trend but this is neutral because
the triple bond is there right it's very
very strong bond to carbon and oxygen
and that's why it is busy it's really if
we got to break this bond the bond
energy is pretty high
that is a 70 kilo because this such a
high point energy carbon monoxide is the
only exception here other oxides
monoxide also you can see Earth has to
be basics because going down the group
the basic nature increase range if you
see this guy is acetic correct these
nays are basic about making this
calculus so going down the basic ratio
increase but the exception is come from
site so it can be asking which exams
also why carbon monoxide is lintel by
the other monocytes are BC this is
because the carbon I'm saying bond is
very strong and almost
we will talk about the resonance
structure of carbon oxide also so if you
draw the resonance structure of carbon
on to we have six one five six this is
one structure the understructure can be
carbon five here because it is giving
money lectrons to carbon also gets a
positive charge
Carbon gave a negative charge the
language structure can be carbon gets a
positive charge
so the resonance if you see the razor
exactly sweet structure for Cabo website
and the residence of it gets extra
stability and becomes let's talk about
the Hydra is now so this is carbon
family elements they combine with
hydrogen to form covalent hydrate speed
mode they almost form covalent hydrides
example alkanes all kinds of mean
silicon is I mean this is the example
the hydrates we have right you know the
ch4 is these hydrates you see the
thermal stability of this hydrates
decreases as we go down the group and a
tendency to form this hydride also
degrees
because carbon forms more nitrites maybe
lead forms lead hydrides hpc right all
the hydrates of carbons are pretty
stable with Heenan on but the lead hydro
itself pretty unstable so you can say
that if you go down the stability of
hydrates decrease and since the
stability degrees it's really rare to
form hydride as you go down the let's
talk about the reaction with water
carbon silicon germanium they are not
impacted with but the team carbon
silicon integral is done we talked about
the team tin will react with hot water
this team deform dioxide and gives
divergence so the sting reacts with what
water to give dye excites and dyeing
everything else and then let also it
forms a protective layer is similar to
el maryam the lead very reacted with
water it forms immediately forms a
protective oxide and which helps lead
which helps led in saving itself it
won't reacted whatever X talk about the
reaction intelligence so most of the
elements the carbon family family they
form halides the formula MX 2 or M X 4
because oxidation state is plus 4n plus
2 way they form Gimli mx2 in Amex for
directly when we activate the halogens
but carbon is something which does not
react directly it forms halogen but
halide word but doesn't form halide
directly and most of these halides are
covalent in nature these central item in
this halide carbon family atoms it
generally go sp3 hybridization except
these values because they are any but
since they are mx4 rights they generally
go for sp3 hybridization and the city
will be stability of this Hawaii
increases as we moved on
stability of dihalides I'm talking about
why because as we go down the class 2
oxidation state is more prominent right
so the stability of dihalides increasing
example if you see PB be led to chloride
is more stable than lead EBC L for it
because dihalide stability increase as
we put on the group because the plus 2
oxidation state is more stable as we
worked on them because of inert pair
effect example in this right PB x2 is
more stable than BB export does let's
state but if you talk about germanium
then GE x4 is more stable than g xj g
plus 4 is more stable and for lead last
use moster that's why we see in the lead
PB x4 is more stable than Pb Pb x2 is
more stable than PB x 4 but in case of
germanium plus 4 is more stable then
just let us talk about the hydrolysis of
halogens should accept CCL 4 other tetra
to right with ham TBC or something
they easily hydrolyzed with water
because the central atom can accommodate
2 lone the pair of electrons from oxygen
but since the carbon is small in size it
cannot accommodate 8 but other than
example as I see a pool right this can
accommodate the lone pair from hydro
swatter and it can see this will replace
the fluid molecules which and if you
replace number one all you get this acid
right so CCL 4 is not able to hydrolyze
because the carbon size is smaller it
will not be able to handle this fish
molecules the bigger in size right so as
I told I'd same one Bobby should be had
4 BC every and BSU same thing here we
have
CCL 4 carbon can handle chlorine so
chlorine over it but it cannot handle o
OS molecules around it correct so except
systems for other
tetrachloride explains hydrolyze the
water where all these fluid molecules
are replaced with
right hope you understand this thank you
