Solution

The correct option is D CF>CCl>CBr>CI
In CF there is 2p2p overlapping involved, in CCl the overlapping involved is 2p3p whereas for CBr and CI the overlapping involved are 2p4p and 2p5p respectively. The bond length for the various type of overlapping can be given as;
2p2p<2p3p<2p4p<2p5p

As we know that Bond energy1Bond Length

The order of bond energy is:
CF>CCl>CBr>CI
