Question

Stability increases, as the energy ___________

(a) increases

(b) doesn’t change

(c) decreases

(d) increases and then decreases

The question was posed to me by my school principal while I was bunking the class.

The origin of the question is Molecular Orbital Theory topic in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

Right choice is (c) decreases

The explanation is: As the stability increases, the energy of that substance decreases. The higher the energy, the less stable the molecule. So stability is inversely proportional to the energy. This can be seen in any part of the universe.
