Question

. The BCl, is a planar molecule whereas NCl3is pyramidal,
because
(a) B-Cl bond is more polar than N-Cl bond
(b) N-Cl bond is more covalent than B-Cl bond
(c) nitrogen atom is smaller than boron atoms
(d) BCl, has no lone pair but NCl3 has a lone pair of
electrons.​

Answer 1

Answer:

(d)

Explanation:

the pyramidal structure is due to lone pair present in N- atom.

Answer 2

Answer:

(D) BCl has no lone pairs but NCl3 has a lone pair of electrons
