NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements about molecular orbitals and their characteristics is correct?
The bonding molecular orbital is formed by the constructive interference of atomic orbitals.
Antibonding molecular orbitals have lower energy than bonding molecular orbitals.
A molecule is stable if the number of electrons in antibonding orbitals exceeds those in bonding orbitals.
The molecular orbital theory does not explain bond lengths or dissociation enthalpies in diatomic molecules.
Correct Answer
Detailed Explanation
The bonding molecular orbital is indeed formed by the constructive interference of atomic orbitals, as stated in the explanation of molecular orbitals. Option B is incorrect because antibonding orbitals are higher in energy than bonding orbitals. Option C is incorrect since stability requires more electrons in bonding orbitals than in antibonding. Option D misrepresents molecular orbital theory, which helps explain bond characteristics.
