Question

The correct statement among the following is

• A. ${(SiH3)3N}$ is pyramidal and more basic than ${(CH3)3N}$
• B. ${(SiH3)3N}$ is planar and more basic than ${(CH3)3N}$
• C. ${(SiH3)3N}$ is pyramidal and less basic than ${(CH3)3N}$
• D. ${(SiH3)3N}$ is planar and less basic than ${(CH3)3N}$

Answer 1

Answer: (D)

${(SiH3)3N}$ is planar and less basic than ${(CH3)3N}$

Answer 2

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.
