Q46.In which of the following ionization processes, the bond order has increased and the magnetic behaviour has changed? (1) C2 ⟶C+2 (2) NO ⟶NO+ (3) O2 ⟶O+2 (4) N2 ⟶N+2

What This Question Tests

This question tests the ability to apply Molecular Orbital Theory to determine bond order and magnetic properties for diatomic species and their ions, then identify the process where both change as specified.

Concepts Tested

Molecular orbital configurationBond order calculationMagnetic properties (paramagnetism/diamagnetism)

Formulas Used

Bond order = 1/2 (Number of electrons in bonding MO - Number of electrons in antibonding MO)
