NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements about molecular orbitals is correct?
Molecular orbitals are polycentric and the number formed is equal to the number of combining atomic orbitals.
Antibonding molecular orbitals have lower energy than bonding molecular orbitals.
Molecular orbitals are filled according to the Hund's Rule only.
Bonding molecular orbitals are formed by the subtraction of atomic orbitals.
Correct Answer
Detailed Explanation
Molecular orbitals are indeed polycentric, and the number of molecular orbitals formed equals the number of combining atomic orbitals, as stated in the NCERT context. Antibonding orbitals are higher in energy compared to bonding orbitals, which makes option A the correct statement.
