JEE · NEET Previous Year Question

$When ψ_{A} and ψ_{B} are the wave functions of atomic orbitals, then σ^{*} is represented by :$

Topic: JEE PYQ

Answer: B. Full step-by-step solution below.

A $ψ_{A} + 2 ψ_{B}$
B $ψ_{A} - ψ_{B}$
C $ψ_{A} + ψ_{B}$
D $ψ_{A} - 2 ψ_{B}$

Correct answer: B

Solution

(b) Antibonding molecular orbitals are formed by destructive interference of wave functions. (ABMO) σ^{*} = ψ_{A} - ψ_{B}
