Linear combination of atomic orbitals (LCAO) results in the formation of:
Correct answer: D. Bonding and antibonding molecular orbitals
- A. Sigma bond
- B. Pi bond
- C. Bonding molecular orbitals only
- D. Bonding and antibonding molecular orbitals
- E. All of these options
Explanation
According to Molecular Orbital Theory (MOT), two atomic orbitals overlap resulting in the formation of molecular orbitals. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the same phase or in the different phase are known as Bonding Molecular Orbital (BMO) and Antibonding Molecular Orbitals (ABMO) respectively.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
