The bond dissociation energy of `B-F` in `BF_(3)` is `646 kJ mol^(-1)` whereas that of `C-F` in `CF_(4)` is `515 kJ mol^(-1)`. The correct reason for higher `B-F` bond dissociation energy as compared to that of `C-F` in `CF_(4)` is

Options

A. Smaller size of B atom as compared to that of C atom
B. Stronger `sigma` bond between B and F `BF_(3)` as Compared to that between C and F in `CF_(4)`
C. Lower degree of `ppi-ppi` interaction between B and F in `BF_(3)` than that between C and F I `CF_(4)`
D. Significant `ppi-ppi` interaction between B and F in `BF_(3)` whereas there is no possibility of such interaction between C and F in `CF_(4)`

Answer

D
