NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements about molecular orbitals and their properties is correct?
Bonding molecular orbitals are lower in energy than the corresponding antibonding molecular orbitals.
All molecular orbitals have equal energy levels.
Antibonding molecular orbitals always have a higher bond order than bonding molecular orbitals.
Molecular orbitals are formed only from s orbitals of the combining atoms.
Correct Answer
Detailed Explanation
Bonding molecular orbitals indeed have lower energy than their corresponding antibonding molecular orbitals, which is fundamental to molecular orbital theory as indicated in the NCERT context.
