If we apply the HOMO and LUMO concepts in atomic orbitals, we will have HOAO (Highest Occupied Atomic Orbitals) and LUAO (Lowest Unoccupied Atomic Orbitals). What is the LUAO of Na atom? - Answer- 3p Which one is correct about the bond lengths in PCl5? Equatorial bonds are longer because they experience smaller repulsion The axial bonds are shorter because they are far away from other bonds All P-Cl bonds have the same bond length. Axial bonds are longer because they experienc...
