Question

The structure of a molecule of N(SiMe3), is: (a) pyramidal with angle close to 110° (b) T-shaped with angle 90° (c) bent T-shaped with angle close to 89° (d) trigonal planar with bond angle close to 120°​

Answer 1

Answer:

trigonal planer with bond angle close to 120°

Explanation:

trigonal planer with bond angle close to 120

Answer 2

Since Si has vacant d-orbital, Lone pair of nitrogen are involved in back bonding with SiMe3 and this bond will be pie bond. So hybridization of N =SP2, hence geometry is trigonal planar and since N does not have any Lone pair of electrons now, it has no lewis base character.

Hence D is the correct answer
