Type: MCQ-conceptual-Medium-Class 11
According to MO theory which of the following lists ranks the nitrogen species in terms of increasing bond order?
A
N₂²⁻ < N₂ < N₂⁺
B
N₂ < N₂²⁻ < N₂⁺
C
N₂⁻ < N₂²⁻ < N₂
D
N₂ < N₂ < N₂²⁻
Correct Answer
Option B
Detailed Explanation
In molecular orbital theory, bond order is calculated as (number of bonding electrons - number of antibonding electrons)/2. N₂²⁻ has the lowest bond order, followed by N₂, and N₂⁺ has the highest.
