Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Significant $\mathrm{p}\pi -\mathrm{p}\pi$ interaction between B and F in ${\mathrm{BF}}_3$ whereas there is not possibility of such interaction between C and F in ${\mathrm{CF}}_4$.

Lower degree of $\mathrm{p}\pi -\mathrm{p}\pi$ interaction between B and F in ${\mathrm{BF}}_3$ than that between C and F in ${\mathrm{CF}}_4$

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

Stronger $\sigma$ bond between B and F in ${\mathrm{BF}}_3$ as compared to that between C and F in ${\mathrm{CF}}_4$
