NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements about molecular orbitals is correct?
The σ molecular orbital is formed by the constructive interference of atomic orbitals.
The σ* molecular orbital has lower energy than the π molecular orbitals.
Antibonding molecular orbitals always stabilize a molecule.
The bonding molecular orbital is formed by subtracting atomic orbitals.
Correct Answer
Detailed Explanation
The σ molecular orbital is indeed formed by the addition (constructive interference) of atomic orbitals, while the σ* is formed by their subtraction (destructive interference), making option A correct. The other options misrepresent the properties of molecular orbitals as described in the NCERT context.
