why does CO A...

Question

why does CO AND CO+ HAVE SIGMA ANTIBONDING 2s ORBITAL AT HIGHER ENERGY THAN SIGMA AND PIE ANTIBONDING 2P ORTIALS IN MOT

Open in App

Solution

As the 2p orbitals are occupied so they take a lower energy position, the 2s orbital which is also the HOMO orbital has higher energy and is also more reactive. This occurs mainly due to electronegativity difference between C and O.

Q. According to 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 and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbital by an amount
