NEET Chemistry Molecular Orbital Theory Assertion Reason Question
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.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
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.
