When ( _ A ) and ( _ B ) are the wave functions of atomic orbitals,...

When (\psi_{\mathrm{A}}) and (\psi_{\mathrm{B}}) are the wave functions of atomic orbitals, then (\sigma^*) is represented by :

Options

  1. A(\psi_{\mathrm{A}}+2 \psi_{\mathrm{B}})
  2. B(\psi_A-\psi_B)
  3. C(\psi_{\mathrm{A}}+\psi_{\mathrm{B}})
  4. D(\psi_A-2 \psi_B)

Correct answer

B. (\psi_A-\psi_B)

Step-by-step solution

Antibonding molecular orbitals are formed by destructive interference of wave functions. (ABMO)σ∗=ψA−ψB(\mathrm{ABMO}) \sigma^*=\psi_{\mathrm{A}}-\psi_{\mathrm{B}}
