MHT CET Chemistry question

Compounds with high heat of formation are less stable because [KCET 2002]

(A)High temperature is required to synthesis them
(B)Molecules of such compounds are distorted
(C)It is difficult to synthesize them
(D)Energy rich state leads to instabilityCorrect

Answer: (D)

Solution

A highly positive heat of formation means the compound lies at a high energy level compared with its elements, and such an energy-rich state tends to release energy
