Question

The number of pie bonds and sigma bonds in the structure benzene-C triple bond N
1.8,5
2.8,6
3.3,8
4.5,13

Answer 1

Note that there are total 6 (C-C) sigma bonds and 6 (C-H) sigma bonds. Benzene also has 3 (C=C) pi bonds. So, there are 12 total sigma bonds and 3 pi bonds in benzene.

but one carbon containing nitrogen triple bond

so option is 4. 5,13
