The number of nodal planes present in ^ * ~s antibonding orbitals is

Options

  1. A1
  2. B2
  3. C0
  4. D3

Correct answer

A. 1

Step-by-step solution

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.
