Question
The bond dissociation energy of B - F in BF3 is 646 kJ mol-1 whereas that of C-F in CF4 is 515kJ mol-1. The correct reason for higher B-F bond dissociation energy as compared to that of C - F is :
Options
A.smaller size of B-atom as compared to that of C - atom
B.stronger σ bond between B and F in 3 BF as compared to that between C and F in CF4
C.significant pπ - pπ interaction between B and F in BF3 whereas there is no possibility of such interaction between C and F in CF3.
D.lower degree of pπ - pπ interaction between B and F in BF3 than that between C and F in CF4.
