The correct statement among the following is:

Options

  1. AS i H 3 3 N is planar and less basic than C H 3 3 N
  2. BS i H 3 3 N is pyramidal and more basic than C H 3 3 N
  3. CS i H 3 3 N is pyramidal and less basic than C H 3 3 N
  4. DS i H 3 3 N is planar and more basic than C H 3 3 N

Correct answer

A. S i H 3 3 N is planar and less basic than C H 3 3 N

Step-by-step solution

l p of N in N C H 3 3 is free to donate while in N S i H 3 3 l p is involved in back bonding so it is not easy to donate hence it is less basic. Due to back bonding it is planar and sp 2 hybridised.
