Assertion Bond order in a molecule can assume any value positive integral or fractional value including zero
Reasoning It depends on number of electrons in the bonding and antibonding orbitals .

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
D

S-1:Bond order may be a positive, whole number or fractional values not negative when `N_B gt N_A`
S-2: Bond order =`("No . Of electron in bonding MO's -No of electrons in anti-bonding MO's")/2`
