Question

A bond dissociation energy is A) The energy required to remove an electron from an atom. B) The energy released when an ionic compound dissociates in water. C) The energy required to break a covalent bond. D) The energy produced in a chemical reaction that breaks chemical bonds.

Answer 1

Answer:

The energy required to break a covalent bond

Explanation:

When a chemical bond is formed, energy is released. When a chemical bond is broken, energy is absorbed.

We define the bond dissociation energy as the energy required to break a covalent bond. The process of covalent bond cleavage is endothermic hence energy is absorbed for the process to occur.
