STANDARD Chemistry Molecular Orbital Theory MCQ Question

Type: MCQ-conceptual-Medium

The electronic configuration of carbon is 1s²2s²2p². There are 12 electrons in C₂. The correct electronic configuration of C₂ molecule is

A

(σ1s)²(σ1s)²(σ2s)²(σ2s)²(σ2p₂)ₓ

B

(σ1s)²(σ1s)²(σ2s)²(σ2s)²(π2pₓ = π2pᵧ)

C

(σ1s)²(σ1s)²(σ2s)²(σ2s)²(π2pₓ = π2pᵧ)

D

(σ1s)²(σ1s)²(σ2s)²(σ2s)²(π2pₓ = π2pᵧ)

Correct Answer

Option B

Detailed Explanation

The correct electronic configuration for C₂ is (σ1s)²(σ1s)²(σ2s)²(σ2s)²(π2pₓ = π2pᵧ) because it follows the molecular orbital theory for diatomic molecules.
