Chemistry-Molecular Orbital Theory

NEET Chemistry Molecular Orbital Theory Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): Molecular orbitals formed from 2p x and 2p y orbitals are symmetrical around the bond axis. | Reason (R): π and π* molecular orbitals have larger electron density above and below the inter-nuclear axis.

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 D

Detailed Explanation

According to the NCERT context, molecular orbitals from 2p x and 2p y are not symmetrical around the bond axis, as they have positive and negative lobes, while π and π* orbitals have larger electron density above and below the axis.
