Question

5. (SiH3)3N is a planer while (CH3)3N is pyramidal in shape. Reason

Answer 1

Answer:

The Nitrogen atom has a hybridization of sp³. ... In (CH3)3 N has two lone pairs, hybridization is sp3. and pyramidal shape. But in (SiH3)3 N has two lone pairs, due to presence of vacant d orbital in Si atom, lone pair of N is shifted to vacant d orbital so it's hybridisation is sp2 with trigonal planar geometry.
