$\mathfrak{\green{Answer.}}$Carboxylic acids, esters, and other acid derivatives. The functional group present in a carboxylic acid is a combination of a carbonyl group and a hydroxyl group; however, the resulting carboxyl group ( -COOH) possesses properties that are unlike those present in aldehydes/ketones and alcohols.

Explanation:

$<p style ="Color:red; font-family: cursive; background:black;font size25px;"> A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH) attached to an R-group. The general formula of a carboxylic acid is R–COOH, with R referring to the alkyl group. Carboxylic acids occur widely. Important examples include the amino acids and fatty acids.$
