The number of nodal planes present in \(\sigma^{*} \mathrm{~s}\) antibonding orbitals is

  1. A 1
  2. B 2
  3. C 0
  4. D 3
Verified Solution

Answer & Solution

Correct Answer

(A) 1

Step-by-step Solution

Detailed explanation

In an antibonding molecular orbital, most of the electron density is located away from the space between the nuclei, as a result of which there is a nodal plane ( a plane at which the electron density is zero) between the nuclei.
