Electron dot structure Examples - Carbon & Compounds, Science, Class 10 Video Lecture

hello friends this video on carbon and
its compound part 13 is vodka bar exam
fear calm no more fear from exam before
watching this video please make sure
that you have watched part 1 by 12
let us draw the electron dot structure
for cyclo hexane a cycle so there are
six the carbon C 6 H 2 L is my formula
of cyclohexane so I have 1 2 3 4 5 & 6 6
carbons to hydrogen's let me in log with
each correct
each I am drawing correct all hydrogen
has one term so let me draw one electron
carbon has four so you can draw 4 1 2 3
4 1 2 u 2 1 2 3 4 right 1 2 3 4 5 1 2 3
1 2 3
see the way I am drawing is I'm drawing
such that this is linear to hydrogen and
I can join these so the next is I have
to join carbon hydrogen bonds these
bonds let me join this is done
correct now if you see I can join these
two carbon you can join these two come
in join these gangs so now if you see I
got the structure and now I see any
carbon it has eight now this carbon had
four got two two from sharing with the
hydrogen 2 plus 4 is 6 1 in this carbon
1 from this carbon 6 plus 2 is 8 so any
carbon if you take this guy if you take
it had forgotten from hydrogen 6 plus 6
and when it got from this carbon 1 from
this carbon so each and every carbon has
8 things of 8 electrons they all
saturated they are all happy and does
this come on let's do the same thing for
benzene benzene has this formula c6h6 so
let's do this 6 carbon and hydrogen 6
hydrogen's well put one into each other
correct and then alpha 2 1 nitrogen's
carbon 3 1 4 here who here oh here
Moop all right let's join in the
carbon-hydrogen okay now let's draw this
guy's this guy's is there is this guy
also so this guy this guy and this now
if you see so many freaking lectrons
eyes let me join this guy
let me knowing this guy and this is my
electron structure so if you see any any
CD has double bond in this and this is
my steel pins now somehow if we can ask
why I am drawing in this fashion why
can't I draw a straight benzene one two
three four five six right then I can add
some hydrogen here six hydrogen's and
then again I had this triple bonds
correct there's a doable option why
should I do this because that's the
possible thing I can do I can create a
straight chain also for c6h6
you can create a straight chain also in
fact that was the assumption see nobody
knew the structure of benzene a layer
scientists used to assume that benzene
is of this fashion straight chain only
benzene was supposed to be a fighting
and they should draw for like this but
they aren't convinced dry because you
draw like this it will have triple bonds
right it will have triple bonds in lab
you triple bond like this it will have
another but also it will have something
like this let me show you this guy is
one one mean this guy is one team's mean
for this there is one HP yeah these are
structure if you see right one two three
six hydrogen atoms
this is of OCC's s6 I think they use
chose you this is the structure but it
doesn't match the property because
either two
dad this is alkyne is high reactive but
they found that benzene is not reactive
confused white is happening generally
all the organs are not reactive why this
guy is not reactive right then this one
scientists showing that rain that maybe
the benzene is structured in this
fashion and then he proposed this model
that benzene is starch it in this
fashion and this explained why bender is
not reactive correct and then finally
when the chemistry explore the science
evolved and they got better instruments
then they actually saw that structure of
menu looks like this correct there's a
whole story involved in this right so
with the C's X days you can form a
formula like this also but this is not
correct formation because for benzene
when we saw actually using instrument
the scientists saw that the camera looks
like and that's the reason video study a
topic called isomers in hydrocarbons
where the same structure the same form
light has it has touches so we'll study
that just understand in this case don't
confuse don't come to me and say that
why can't write like this we can write
like this because it does not like this
it is based on the observation they
found that being in looks like this
correct so it may be some other
component it is cs6 only but this is not
Benjamin is this very ugly right it may
be there may be a compound called cs6
whose name will find out in the next few
slides but which will not be busy should
be CC cs6 but not really so let's draw a
same thing for cyclo pentene
cyclopentane the formula is C Phi
wasting hero so I can buy it a straight
one also aliphatic chain but that's not
the one looking for it cyclo that means
the cyclic cyclic is there so I have one
two three four high carbon 10 hydrogen's
I could do with each right and he do
with each then I have a hydrogen atoms
he should will have one and I have
carbon each you have four okay now
ajamgarh is your own once we are done
with this carbon hydrogen bond somebody
comment I am done with now I join carbon
double bonds and this is what I get
you see all the items are all the carbon
has none eight share letters this is
some of my cyclic wait
