Question

Which of the following is phenyl ethanoate?

Answer 1

Hint- Here, we will proceed by discussing all the organic compounds given in the options of the problem. We will write down the names of these compounds along with basic features of these compounds.

Complete answer:
The compound structure as given in the first option corresponds to the methyl benzoate structure. Methyl benzoate is a compound organic to it. This ester has ${{\text{C}}_6}{{\text{H}}_5}{\text{COOC}}{{\text{H}}_3}$ as its chemical formula. It is a colorless liquid which is moderately water-soluble but miscible with organic solvents. Methyl benzoate has a good fragrance, highly reminiscent of the feijoa tree fruit and is used in perfumery. It is also used as a solvent and as a pesticide for attracting insects such as orchid bees.
The compound structure given in the second choice matches phenoxyacetic acid structure. Phenoxyacetic acid is a monocarboxylic acid, which is the glycolic acid derivative O-phenyl. A 2-phenoxyethanol metabolite, it is used in the manufacture of pharmaceuticals, pesticides , fungicides, and dyes. It has a role as a human xenobiotic metabolite, a metabolite of Aspergillus, a retardant for plant growth and an allergen. It is a monocarboxylic acid and a flavoring alcohol. It is derived from a glycolic acid. It is a phenoxyacetate Conjugate Acid.
The compound structure given in the third choice coincides with the phenyl ethanoate structure. Phenyl acetate is an acetate ester obtained by formal acetic acid condensation of the phenol. This is a phenyl acetate member, and a benzenes member. It originates from a phenol.
The structure of the compound given in the fourth option corresponds to the structure of ethyl benzoate. It is the ester which is formed by benzoic acid and ethanol condensation. This is an almost insoluble colorless liquid in water but miscible with other organic solvents. Ethyl benzoate, as with many volatile esters, has a pleasant odor described as sweet, winter-green, fruity, medicinal, cherry and grape. This is a part of many artificial fruit aromas and fragrances.

Therefore, option C is correct.

Note- Phenyl ethanoate and hydrogen chloride gas are formed together. Sometimes, first the phenol needs to be changed to make the reaction smoother. Benzoyl chloride, for example, has the formula ${{\text{C}}_6}{{\text{H}}_5}{\text{COCl}}$. The group -COCl is placed directly on a benzene ring. This is much less reactive than simple acyl chlorides such as ethanoyl chloride.
