Question

A positive overlap is same as ________

(a) out-phase overlap

(b) negative overlap

(c) zero overlap

(d) in-phase overlap

I had been asked this question in my homework.

The above asked question is from Valence Bond Theory topic in division Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

Correct option is (d) in-phase overlap

To explain I would say: A positive overlap results in bond formation. When 2 p-orbitals are in phase, both the positive lobes overlap, thus creating a positive overlap and result in the bond formation, thus it is called in-phase overlap.
