Indicate the sigma and pi bond in the following molecules : CH2Cl2

Text Solution

Verified by Experts

The correct Answer is:
D
Theoretical heat of hydrogenation of benzene = (Actual heat of hydrogenation) + (Resonance energy)

=-205 - 152 =- 357
Enthalpy of hydrogenation of ,
`=(-357)/(3) = - 119` kJ/mol
