ChemistryEasy141×since 2002Q249The 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 isAstronger σ\sigmaσ bond between B and F in BF₃ as compared to that between C and F in CF₄Bsignificant pπ−pπp\pi - p\pipπ−pπ interaction between B and F in BF₃ whereas there is no possibility of such interaction between C and F in CF₄Clower degree of pπ−pπp\pi - p\pipπ−pπ interaction between B and F in BF₃ than that between C and F in CF₄Dsmaller size of B - atom as compared to that of C- atom.Check answerSkip
