Question:

The bond dissociation energy of B–F in BF₃ is 646 kJ mol^-1 whereas that of C–F in CF₄ is 515 kJ mol^–1. The correct reason for higher B–F bond dissociation energy as compared to that of C–F is

(A) Significant p? – p? interaction between B and F in BF₃whereas there is no possibility of such interaction between C and F in CF₄.

(B) Lower degree of p? – p? interaction between B and F in BF₃ than that

between C and F in CF₄

(D) Stronger bond between B and F in BF₃ as compared to that between C and F in CF₄.
