Select which type of overlapping is responsible for π -character in S i – N bond of H 3 S i N C O

Options

  1. A3 p π → 2 p π
  2. B2 p π → 2 p π
  3. C3 d π ← 2 p π
  4. D3 d π ← 2 d π

Correct answer

C. 3 d π ← 2 p π

Step-by-step solution

π - character is due to 3 d π ← 2 p π back bonding between 3 d orbital of S i and 2 p orbital of N.
