Example Lewis dot structure - Chemical Bonding & Molecular Structure Video

hello friends this feeding on chemical
morning part 8 is brought to you by exam
fear calm no more fear from exam before
watching this video please make sure
that you watch part 1 to part 7 so let's
draw the structure of c2h2
so carbon has 4 electrons carbon has 4
electrons valence electrons and there
are 2 carbons whoa 2 hydrogen has one
valence electron two hydrogen atoms
total is 10 valence electron it's
arranged in this fashion c2h2
anybody is connected so that was Center
so we can hit in this fashion so we
start with 10 valence and we have three
bonds now right so we need six electrons
gone 4 3 1 so we have 4 valence left
let's try to satisfy this carbon this
carbon has now 4 electrons right 1 2 3
input to be happy it needs four more we
gave for this later so we are left with
0 well as later on and this carbon is
not happy right so this carbon told ok
I'll give one leg front view and form a
double bond so let's start with the new
structure this fashion this is gone so
let's start again from fresh we have 10
valence electron in the bonding normally
eat electron because we have 4 bonds
each electron is needed for hold on we
have 2 electron donating this carbon has
6 electrons now write 1 2 4 5 6 so it
needs 2 electron to be happy this carbon
is happy so we have this carbon happy
but we are left with 0 valence electron
and this carbon is not happy it has 6
electrons this guy is sad so again this
carbon todo lo que el pay once more with
you so now this carbon is falling in
tipple bond with this carbon again
redraw the structure
so we start with ten valence electron we
have 3 + 2 5 are born that means we need
10 valence electron 4 5 1 so we are left
with zero balance left so in this case
if everybody is happy that means this is
my structure let's see this carbon has 8
electron this carbon has 8 electrons
this hydrogen has 2 electrons in this
hedges 2 electron service everybody's
happy
since everybody is happy this is my
structure right because my carbonyl
carbon hydrogen all that under this
model is happy this enough - that's the
example of oxygen oxygen has 6 valence
electron and they're 2 molecules you
have 2 lvls liquid let us join these
oxygen by single bond start with 6 12
valence electron and I consume 2
electrons for one bond I am left with 10
levels this oxygen has two electrons
normal and you eat electrons to be happy
so I will give 6 electron to this guy
this is 1 this is 2 so 6 electrons I
give you oxygen 1 I am left with 4
electrons this oxygen 2 has 2 electrons
it means 6 electrons to be happy but we
have only 4 electrons to be here this
guy oxygen to atom need 6 electrons to
be happy but we are willing to valence
electrons this oxygen to his sad so what
do ROM oxygen will say ok do one more
sharing with you don't be sad so we'll
start fresh here with a double bond
let's cross this so we have suffered
with 12 Alan's bond well as electron so
we have a double bond double bond needs
4 electron or to 1 so we are left with 8
electrons move let's see first oxygen
this is oxygen is also in two oxygen one
has four electrons form
right one two three four and it needs
four more so let's give four electrons
to the service go through oxygen one so
we are left with four oxygen four
electrons actually and this oxygen is
happy
let's see oxygen to oxygen two also has
four electron and that's why it needs 8
minus 4 is 4 electrons and we have four
electrons so let's give this whole
electron to this oxygen so this is
oxygen is also happy I am left with zero
where electron now but this oxygen one
and two both are happy since both are
happy right both both electrons are with
the oxygen were happy I will say that
this is mine let me stretch
hey because ladies structures say that
all the atoms in the molecule has to be
happy that's all the molecules all the
atoms in the molecule has to be stable
to give a proper structure
