Answer 1

(i) ( C₆H₆ ) 

There are six C – C sigma (−) bonds, six C–H sigma (−) bonds, and three C=C pi (−) resonating bonds in the given compound. 

(iv) CH2 = C = CH2 

There are two C–C sigma (−) bonds, four C–H sigma (−) bonds, and two C=C pi (−) bonds in the given compound. 

(v) CH3NO2

 There are three C–H sigma (−) bonds, one C–N sigma (−) bond, one N–O sigma (−) bond, and one N=O pi (−) bond in the given compound.
