Answer 1

Benzene contains 6 C−C sigma bonds, 3 C=C pi bonds and six C−H sigma bonds respectively.

Cyclohexane contains 6 C−C sigma bonds and 12 C−H pi bonds.

Dichloromethane contains 2 C−H sigma bonds and 2 C−Cl sigma bonds.

Allene contains 2 C−C sigma bonds, 2 C=C pi bonds and 4 C−H pi bonds.

Nitromethane contains 3 C−H sigma bonds, 1 C−N sigma bond, 2 N−O sigma bonds and 1 N=O pi bond.

N-methyl formamide  contains 2 C−N sigma bonds, four C−H sigma bonds, one N−H sigma bond, one C−O sigma bond and one C−O pi bond.
