NEET Chemistry Molecular Orbital Theory Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 11

Assertion (A): A bonding molecular orbital has lower energy than the corresponding antibonding molecular orbital. | Reason (R): In a bonding molecular orbital, electron density is concentrated between the nuclei, reducing repulsion between them.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option A

Detailed Explanation

The assertion and reason are both true, and the reason correctly explains the assertion. The electron density between the nuclei in a bonding molecular orbital leads to reduced repulsion and increased stability, thus resulting in lower energy compared to an antibonding molecular orbital.
