Question

The strength of covalent ___________  extent of overlapping of orbitals.

(a) may be or may not be related

(b) is independent on

(c) is dependent on

(d) is not related to

This question was posed to me in exam.

This intriguing question comes from Valence Bond Theory in chapter Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

Right answer is (c) is dependent on

To explain: As per the concept of valence bond theory, the partial merging of atomic orbitals id knowns as overlapping. The extent of overlapping is directly proportional to the strength of the covalent bond, i.e. it is dependent.
