Hello students, let's look at the question.
00:02
This is a reaction of dials elder reaction.
00:14
This is 4 pi plus 2 pi cyclo addition reaction which is thermally induced.
00:21
The product form through those six member cyclic transition.
00:27
And in this reaction there are two reactant.
00:31
One is dine this is dine and dino phil dine and dino file dine and dino file dine is higher occupied molecular orbital ho -mo and dinofo and dinofile homo is represented by 4 pi conjugated system diene while lumo is represented by 2 pi system dinophile.
01:14
Generally dinophiles have electron withdrawing group attached to them which increases the rate on reaction.
01:22
On the other hand, dine have electron releasing group attached to them in general.
01:30
So here this is the reaction.
01:34
In the given question, we can see that electron releasing methyl group are attached to dine, while electron releasing cn group are attached to dynophile.
01:45
Both leads to increase in the rate of reaction.
01:49
Also, the reaction is taken place thermally indicated by symbol, indicated by this symbol, because this is the symbol of heating.
02:01
So the formation, after the reaction, the process, the process, the process...
