NEET Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about molecular orbitals is correct?
A
Bonding molecular orbitals have higher energy than antibonding molecular orbitals.
B
Electrons in bonding molecular orbitals contribute to the stability of a molecule.
C
The number of molecular orbitals formed is less than the number of combining atomic orbitals.
D
Molecular orbitals are always monocentric like atomic orbitals.
Correct Answer
Option B
Detailed Explanation
Electrons in bonding molecular orbitals tend to hold the nuclei together and stabilize a molecule, as stated in the context. Bonding molecular orbitals have lower energy than antibonding ones, and the number of molecular orbitals formed equals the number of atomic orbitals combined.
