Dear students, in this question, this is a heterocyclic ring.
00:06
Assuming the heterocyclic ring to be planner, it is given that this ring is planner, give the number of electrons that are contributed to the pi system of the heterocyclic ring.
00:19
Number of electrons that are contributed to the pi system of the heterocyclic ring by atom 1, atom 2, and atom 3 is not there, so it is not applicable for atom 3.
00:33
Right here not applicable.
00:35
Atom 1, there is pi bond here and the electron pair will be in another orbital.
00:43
So that electron pair cannot be contributed to the conjugate system.
00:49
Therefore, atom 1 cannot contribute.
00:55
So atom 1 has no contribution.
01:02
Now here in the atom 2, the electron pair is present in an orbital...
