BCl3 is a planar molecule whereas NCl3 is pyramidal because

Question 1

(a) BCl3 has no lone pair of electrons but NCl3 has a lone pair of electrons

(b) B—Cl bond is more polar than N—Cl bond

(c) Nitrogen atom is smaller than boron atom

(d) N—Cl bond is more covalent than B—Cl bond

Question 2

Correct option: (a) BCl3 has no lone pair of electrons but NCl3 has a lone pair of electrons

Explanation:

In BCl3 there is sp2 hybridisation (planar) in NCl3 hybridisation is sp3 hence shape is pyramidal
