The highest heat of hydrogenation is shown by which of the following compound? (A) Option 1

(B)

(C)

(D)

Tardigrade Admin · Accepted Answer

Δ H hydrogenation propto (1/stability of alkenes) stability of alkenes. In option (.1.), the π electrons are not in conjugation so alkene is least stable and heat of hydrogenation is maximum.

Q. The highest heat of hydrogenation is shown by which of the following compound?

$Δ H$ hydrogenation $\propto \frac{1}{s t abi l i t yo f a l k e n es}$ stability of alkenes. In option $(1),$ the $π$ electrons are not in conjugation so alkene is least stable and heat of hydrogenation is maximum.
