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 located between the nuclei, reducing nuclear repulsion.
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.
Correct Answer
Detailed Explanation
The assertion and reason are both true and related. The bonding molecular orbital has lower energy due to reduced nuclear repulsion, as the electron density is concentrated between the nuclei, stabilizing the molecule.
