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 is :

Options

1. Asmaller size of B-atom as compared to that of C-atom
2. Bstronger bond between B and F in BF ₃ as compared to that between C and F in CF ₄
3. Csignificant p - p interaction between B and F in BF ₃ whereas there is no possibility of such interaction betw
4. Dlower degree of p - p interaction between B and F in BF ₃ than that between C and F in CF ₄ .
