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 ascompared to that of C-F is:- |
|
Answer» 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`. |
