JEE Main 2024 — 8 April, Shift 2 — Question 60

When ψA\psi_{\mathrm{A}} and ΨB\Psi_{\mathrm{B}} are the wave functions of atomic orbitals, then σ∗\sigma^{*} is represented by :

  1. Option A:

    ψA−2ψB\psi_{\mathrm{A}}-2 \psi_{\mathrm{B}}

  2. Option B:

    ψA−ψB\psi_{\mathrm{A}}-\psi_{\mathrm{B}}

    Correct
  3. Option C:

    ψA+2ψB\psi_{\mathrm{A}}+2 \psi_{\mathrm{B}}

  4. Option D:

    ψA+ψB\psi_{\mathrm{A}}+\psi_{\mathrm{B}}

Answer: 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}}
