Which of the bonding orbital has greater energy comparatively?(a) Both Bonding molecular orbital and Anti-bonding molecular orbital have the same energy(b) The energy of Bonding molecular orbital and Anti-bonding molecular orbital depends on the situation(c) Bonding molecular orbital(d) Anti-bonding molecular orbitalThis question was addressed to me in an interview for job.The origin of the question is Molecular Orbital Theory topic in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer»

Correct choice is (d) Anti-bonding molecular ORBITAL

The BEST explanation: An ELECTRON that enters bonding ORBITALS stabilizes the MOLECULE as it’ in between two nuclei. Whereas when an electron is entered into the anti-bonding orbital, it needs to pull an electron away from the nucleus.
