The BCl3 is a planar molecule whereas NCl3 is pyramidal because :
- BCl bond is more polar than N–Cl bond
- N–Cl bond is more covalent that B–Cl bond
- nitrogen atom is smaller than boron atom
- BCl3 has no lone pair of electrons but NCl3 has a lone pair of electrons
Answer
(D) BCl 3 has no lone pair of electrons but NCl 3 has a lone pair of electrons
