Interpretation: As a hybrid of five contributing structures the given molecule has to be drawn.
Concept Introduction:
Kekule structures:
The double bonds of an aromatic ring shift back and forth very rapidly. The resulted forms or structures cannot be separated and stay in equilibrium. Those structures are known as Kekule structures.

- (a) How will you convert:(i) Benzene to acetophenone (ii) Propanone to 2-Methylpropan-2-ol(b) Give reasons :(i) Electrophilic substitution in benzoic acid takes place at meta position.(ii) Carboxylic acids are higher boiling liquids than aldehydes, ketones and alcohols of comparable molecular masses.(iii) Propanal is more reactive than propanone in nucleophilic addition reactions.arrow_forward(a) Although phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol. Give two reasons.(b) How will you bring about the following converstions?(i) Propanone to propane (ii) Benzoyl chloride to benzaldehyde(iii) Ethanal to but-2-enalarrow_forward1) The carbon-oxygen double bond present in aldehydes and ketones is very polar.
