Higher B-F (in BF3) bond dissociation en...

Higher B-F (in `BF_3`) bond dissociation energy as compared to that of C-F (in `CF_4`) is due to-

A

stronger `sigma` -bond between B and F in `BF_3` as compared to that between C and F in `CF_4`

B

significant `p pi-p pi` interaction between B and F in `BF_3` whereas there is no possibility of such interaction between C and F in `CF_4`

C

lower degree of `p pi-p pi` interaction between B and F in `BF_3` than that between C and F in `CF_4`

D

smaller size of B -atom as compared to that of C -atom
