Free notes + solved JEE problems for this lesson: https://rankdeterminant.com/go/yt-che... All lessons of this unit:    • JEE 2027 Chemistry | Unit 3 Chemical Bondi...   How molecular orbitals form, for JEE: the LCAO idea, why n atomic orbitals give n molecular orbitals, the bonding MO (psi A plus psi B, lower energy, density between the nuclei), the starred antibonding MO (higher energy, a node between the nuclei), the three conditions for combining, which 2s and 2p pairs give sigma and pi MOs, and two solved examples with the classic traps.
