Which one of the following species will have maximum bond dissociation energy?

The correct order of bond energy (in kJ/mol) of the following molecules is

Statement 1 : Xenon fluorides are well known and stable but the corresponding chlorides have not been reported. Statement 2: Xe-F bond is more strong than Xe-Cl bond and F_2 molecule has low bond dissociation energy than that of Cl_2 molecule.

Assertion : Xenon fluorides are well known and stable but the corresponding chlorides have not been reported. Reason : Xe-F bond is more strong than Xe-Cl bond and F_2 molecule has low bond dissociation energy than that of Cl_2 molecule.

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 the : smaller size of B atom as compared to that of C atom.; stronger sigma bond between B and F in BF_3 as compared to that between C and F in CF_4 ; significant p pi-p pi interactions between B and F in BF_3 , whereas there is no possibility of such interaction between C and F in CF_4 ; lower degree of p pi-p pi interactions between B and F in BF_3 than that between C and F in CF_4
