Question

The enthalpy of hydrogenation of cyclohexene is
-119.5 kJ mol-?. If resonance energy of benzene is
- 150.4 kJ mol-, its enthalpy of hydrogenation
would be

(1) -358.5 kJ mol-1
(2) -508.9 kJ mol-1
(3) -208.1 kJ mol-1
(4) -269.9 kJ mol-1​

Answer 1

Answer:

-208.1kjmol^-

Explanation:

enthalpy of hydrogenation =3of enthalpy of hydrogenation of cyclohexene -resonance energy of benzene
