Here the question is why is benzene less reactive towards electrophiles than an alkyne even though it has more pi electrons than an alkyne 6 versus 2 yes in case of benzene first of all we have to see that electrophiles that means electrophilic reagents which can attack where the electrons are more in case of benzene, 6 pi electrons are present.
00:35
So, benzene is actually this structure.
00:48
6 pi electrons are present in benzene.
00:51
And in case of alken, if 6 -membered compound is taken, alken should be 1, 2, 3, 4, 5, 6.
01:04
Double bond can be present anywhere, but this is the double bond here.
01:08
Only one number.
01:11
This is alky.
01:13
Here only two electrons are present, pi electron, and here six pi electrons are present.
01:27
The question is why electrophilic substitution reaction or addition reactions are less in case of benzene as compared to alky? first reason is benzene is cyclic.
01:47
This is the difference.

Planar and completely conjugated, conjugated structure...
