Question

Which of the following is not classified as a derivative of a carboxylic acid?

• A. Alcohol
• B. Ester
• C. Acid halide
• D. Amide

Answer 1

The correct option is A

Alcohol

Explanation of the correct option:

Option A is correct:

1. The derivative of a carboxylic acid ($\mathrm{COOH}$) is the compound in which the Hydrogen of a carboxylic acid is replaced by some other compound.
2. Alochols ($\mathrm{OH}$) are not the derivatives of carboxylic acids.

Explanation of the incorrect options:

Options B, C, and D are incorrect:

Examples of derivatives of Carboxylic acid are: -

Amide (${\mathrm{CONH}}_2$): Amides seem as derivatives of carboxylic acids wherein the hydroxyl organization has been changed through amine or ammonia.

Ester ($\mathrm{RCOOR}’$): The use of acid and alcohols in the conversion of carboxylic acids to esters (Fischer Esterification) An ester is generated when a carboxylic acid is combined with an alcohol and an acid catalyst (together with water). The Fischer esterification is the name given to this reaction. As a result, the ester is a carboxylic acid by-product.

Acid halide ($\mathrm{COCl}$) : Acyl halides (additionally called acid halides) are one instance of an acid derivative. In this instance, the -OH group has been changed with the aid of using a chlorine atom; chlorine is the maximum normally used acid halide

Hence, option A is correct.

Alcohol is not classified as a derivative of a carboxylic acid.
