Match List-I with List-II

List-I:
(A)

Ψ_{MO} = Ψ_{A} - Ψ_{B}

(B)

μ = Q \times r

(C)

\frac{N _{b} - N _{a}}{2}

(D)

Ψ_{MO} = Ψ_{A} + Ψ_{B}

List-II:
(I) Dipole moment
(II) BMO
(III) ABMO
(IV) Bond order

Answer: A → III, B → I, C → IV, D → II

Solution

Matching the molecular orbital theory concepts:

(A) $Ψ_{MO} = Ψ_{A} - Ψ_{B}$ represents the antibonding molecular orbital (ABMO), formed by destructive interference.
(B) $μ = Q \times r$ is the formula for dipole moment (charge × distance).
(C) $\frac{N _{b} - N _{a}}{2}$ is the formula for bond order (bonding electrons minus antibonding electrons, divided by 2).
(D) $Ψ_{MO} = Ψ_{A} + Ψ_{B}$ represents the bonding molecular orbital (BMO), formed by constructive interference.

Correct matching: (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
