Assertion (A): Bond energy of CI-CI bond...

Assertion (A): Bond energy of CI-CI bond is more than F-F bond.
Reason (R ): Shorter the bond length, stronger the bond, more is the bond energy.

A

Both A and R true and R is the correct explanation of A

B

Both A and R true and R is not a correct explanation of A

C

A is true but R is false

D

A is false but R is true

Text Solution

Verified by Experts

The correct Answer is:
B
Reason. Lower bond energy of `F_2`, despite shorter bond length is due to repulsion between lone pairs on two F atoms.
