BF3\text{BF}_3 and NF3\text{NF}_3 both are covalent compounds but NF3\text{NF}_3 is polar whereas BF3\text{BF}_3 is non-polar. This is because : a. Nitrogen atom is smaller than boron atom b. N−F\text{N}-\text{F} bond is more polar than B−F\text{B}-\text{F} bond c. NF3\text{NF}_3 is pyramidal whereas BF3\text{BF}_3 is planar triangular d. BF3\text{BF}_3 is electron deficient whereas NF3\text{NF}_3 is not
