Which of the following has orange flavour__________________?
Correct answer: B. octyl acetate
- A. isobutyl formate
- B. octyl acetate
- C. ethyl butyrate
- D. amyl lactate
Explanation
Octyl acetate is an ester with a characteristic orange-like flavour, which is why it is used in flavouring materials. Ethyl butyrate is commonly associated with pineapple flavour, so it is a tempting alternative. The mistake is matching any fruity-smelling ester with orange without recalling the particular ester-flavour association.

About Carboxylic Acid Derivatives
Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
