Hint: Before solving this question, we should know about the resonance, resonating structures of phenol and then find out which one of them is less stable. Resonating structures are the lewis structures of the same compound. They are hybrid structures whose positions of electrons are different but the position of the atom is the same.
Complete answer:
The derivative of aromatic hydrocarbon which has a hydroxyl group, are known as phenols. The molecular formula of it is ${{C}_{6}}{{H}_{5}}OH$. The other names of phenol are benzenol, carbolic acid. It is a volatile solid compound that is white or colorless.
Phenol is represented by four Resonating structures. Resonance helps to stabilize the phenol as well as the phenoxide ion by delocalizing the electrons in the ring. The oxygen atom becomes positive because of the separation of charge that occurs due to the delocalization in phenol whereas in phenoxide ion the delocalization makes it more stable because charge separation does not occur in this. If we have to compare which is the less stable resonating structure, that would be Phenol.
So, Option (A) Phenol
is the correct option.
So, the correct answer is “Option A”.
Note:
The process of delocalizing the electrons in molecules where the bonding cannot be described by just one lewis structure is known as Resonance. In Resonance, Every lewis structure contributes to the formation of the target molecule or ion. One should not mistake the lewis structures being the isomers as only the position of delocalized electrons differs. It is also known as mesomerism.
