Question

The correct statement among the following is

• A. $(SiH_3)_3N$ is pyramidal and more basic than $(CH_3)_3N$
• B. $(SiH_3)_3N$ is planar and more basic than $(CH_3)_3N$
• C. $(SiH_3)_3N$ is pyramidal and less basic than $(CH_3)_3N$
• D. $(SiH_3)_3N$ is planar and less basic than $(CH_3)_3N$

Answer 1

Answer: (D)

nitrogen is $sp^3$ hybrid and pyramidal no back-bonding i.e.more basic
Nitrogen $sp^2$ hybrid and planar due to back bonding and less basic because lone pair is not available for donation.
