The molecule having highest bond enegy is

A

`N -N`

B

`F -F`

C

`C -C`

D

`O -O`

Text Solution

Verified by Experts

The correct Answer is:
C
Single bond energies tend to increase along the period `(rarr)` . But still `(C -C)` bond is the greatest because non bonding `e^(-')s` repulsion is very high in `N -N, O -O` and `F -F` due to small size of atoms, which weakens the respective bonds .
