A square planar complex is formed by hybridisation of which atomic orbitals ?

• A

  $s, p_x, p_y, d_{y z}$
• Correct answer
  B

  $\mathbf{s}, \mathbf{p}_x, \mathbf{p}_y, \mathrm{~d}_{x^2-y^2}$
• C

  $s, p_x, p_y, d_{z^2}$
• D

  $\mathbf{s}, \mathbf{p}_y, \mathrm{p}_z, \mathrm{~d}_{\mathrm{xy}}$

Hence, the correct answer is option: 'B'.
