NEET Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-numerical-Easy-Class 11
Calculate the bond order of O₂ molecule using the molecular orbital configuration: σ1s², σ1s², σ2s², σ2s², σ2p_z², π2p_x², π2p_y², π2p_x¹, π2p_y¹.
A
1.0
B
2.0
C
2.5
D
3.0
Correct Answer
Option B
Detailed Explanation
The bond order is calculated using the formula: (number of electrons in bonding MOs - number of electrons in antibonding MOs)/2. For O₂, it is (8 - 4)/2 = 2.0.
