NEET Chemistry Molecular Orbital Theory MCQ Question
In the context of molecular orbital theory, how do the energies of bonding (σ) and antibonding (σ*) molecular orbitals compare when formed from atomic orbitals ψA and ψB?
σ is lower in energy than σ*
σ and σ* have equal energy
σ is higher in energy than σ*
Energy of σ is independent of σ*
Correct Answer
Detailed Explanation
According to the NCERT context, the bonding molecular orbital (σ) is formed by the addition of atomic orbitals and is lower in energy than the antibonding molecular orbital (σ*), which is formed by their subtraction.
