Ans :-
The less stable alkene or alkyne will have the highest heat of hydrogenation.
Option (D) alkene is most stable due to the presence of conjugation between double bonds, therefore it has lowest heat of hydrogenation.
Therefore, option (b) i.e. B > C > A > D is the answer as it is the only option in which D have least heat of hydrogenation.
Add Answer to:

III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...
