Which one of the following correctly represents the formation of bonding molecular orbital from the atomic orbitals having wave functions ψA and ψB ? ans. ψA + ψB ψA x ψB ψA - ψB ψA / ψB
Question
Which one of the following correctly represents the formation of bonding molecular orbital from the atomic orbitals having wave functions ψA and ψB ? ans. ψA + ψB
ψA x ψB
ψA - ψB
ψA / ψB
Solution
The formation of a bonding molecular orbital from atomic orbitals having wave functions ψA and ψB is correctly represented by ψA + ψB.
Here's why:
Molecular orbitals are formed by the combination of atomic orbitals. This combination can be either constructive or destructive.
In the constructive combination, the wave functions of the atomic orbitals add together, resulting in a bonding molecular orbital. This is represented by ψA + ψB.
In the destructive combination, the wave functions of the atomic orbitals subtract from each other, resulting in an antibonding molecular orbital. This is represented by ψA - ψB.
The other two options, ψA x ψB and ψA / ψB, do not represent the formation of molecular orbitals.
