00:01
Okay, so we have given here different structure.
00:02
We have to show the resonance structures and the stable one also.
00:09
Okay, so here we have a ring which consists of nitrogen atom.
00:17
Double bond is there, there and there, and we have a pair of electron present on this nitrogen.
00:24
Now it is to be noted that this pair of electron do not take part in resonance.
00:28
Okay, so now the double bond can move from here to here then this double bond can move then this double bond can move to this next carbon and that's why we can have another resonance structure like this okay so here both are equally stable okay, okay? in this case both the resinaceous structures are equally stable second one we have given ch3 co ch3 now how can we draw this so we have a carbonyl carbon which is attaching the two methyl groups okay let me draw it again okay so now what we can do here this this oxygen has unbounded electrons right so now this double bond moves here to form the unbounded pair of electron then we will have this carbon with three hydrogen atom as such then this carbon with three hydrogen atoms as such and this carbon atom is single bondedly attached to oxygen atom and now it has three lone pair of electron earlier it had two lone pair of electron okay and now we have a negative charge present on this oxygen atom and positive charge present on this carbon okay now this is more stable okay this is less stable and the reason being this structure we have drawn this is neutral with no charge okay there is no charges there is no positive and negative charges shown with no charges.
03:19
So that's why this is more stable.
03:23
Then we have c part.
03:28
We have given here this ring with two double bond and a positive charge.
03:35
Now what we can do here? this double bond, this positive charge shows that this carbon is electron deficient.
03:43
This double bond will move here to this electron deficient...
