The Molecular Orbital Treatment Of Benzene MDCAT Quiz with Answers

The Molecular Orbital Treatment Of Benzene MDCAT Quiz: The Molecular Orbital Treatment of Benzene The advanced concept of the molecular orbital (MO) theory explains the stability and bonding in the benzene molecule. According to this theory, the six π-electrons of benzene are not localized between the carbon atoms; instead, they are delocalized over the whole ring. It is in this way that molecular orbitals are formed by overlapping p-orbitals of carbon atoms, forming bonding and anti-bonding molecular orbitals. The molecular orbitals of lower energy are the bonding types, and electrons fill these orbitals, giving a very stable structure. This treatment is very essential for explaining the special properties of benzene, such as resistance to addition reactions and aromatic stability. It is very essential that MDCAT students understand this molecular orbital theory for deeper insight into the behavior of aromatic compounds.
