The bond dissociation energy

Significant $\mathrm{p} \pi-\mathrm{p} \pi$ interaction between $\mathrm{B}$ and $\mathrm{F}$ in $\mathrm{BF}_{3}$ whereas there is not possibility of such interaction between $\mathrm{C}$ and $\mathrm{F}$ in $\mathrm{CF}_{4}$.

Lower degree of $\mathrm{p} \pi-\mathrm{p} \pi$ interaction between $\mathrm{B}$ and $\mathrm{F}$ in $\mathrm{BF}_{3}$ than that between $\mathrm{C}$ and $\mathrm{F}$ in $\mathrm{CF}_{4}$

Smaller size of B-atom as compared to that of C-atom

Stronger $\sigma$ bond between $\mathrm{B}$ and $\mathrm{F}$ in $\mathrm{BF}_{3}$ as compared to that between $\mathrm{C}$ and $\mathrm{F}$ in $\mathrm{CF}_{4}$
