Question

esters and amides are considered to be derivatives of carboxylic acids because the oh in the carboxyl group is replaced with another group. true false

Explanation:

Esters are formed when the -OH group in a carboxylic acid (\(R - COOH\)) is replaced by an -OR' group (from an alcohol, \(R' - OH\)) through an esterification reaction (\(R - COOH+R' - OH\ce{<=>[H^+][]}R - COOR'+H_2O\)). Amides are formed when the -OH group in a carboxylic acid is replaced by an -NR'_2 group (from an amine, \(R'_2NH\)) through a reaction (e.g., \(R - COOH + R'_2NH\to R - CONR'_2+H_2O\)). Since in both esters (\(R - COOR'\)) and amides (\(R - CONR'_2\)) the -OH of the carboxylic acid (\(R - COOH\)) is replaced by other groups (-OR' and -NR'_2 respectively), they are considered carboxylic acid derivatives.

True
