PCl 5 is well known but NCl 5 is not.Because,

Options

  1. AN - does not have vacant d -orbital
  2. BP - does not have 2 d orbitals
  3. CBack bonding in NCl 5 is not possible
  4. DN atom is more electronegative so does not forms 5 bonds

Correct answer

A. N - does not have vacant d -orbital

Step-by-step solution

Due to the absence of vacant d orbitals nitrogen cannot form penta halides, so NCl 5 is not formed but PCl 5 is formed as phosphorous has vacant d orbitals
