Theoretical background Carboxylic acid derivatives are organic compounds containing the call group core structure attached to a Y group, which may be an electronegative atom or substitutes.

The Y group acts as a leaving group in necrophilia call substitution. This mechanism is involved in hydrolysis, alcoholisms, and analysis reactions. As strong organic acids, carboxylic acids react with silver nitrate and sodium bicarbonate to form the corresponding carboxylic salts. Among the carboxylic acid derivatives, call halides are the most reactive and amides the least. Thus, the reactions of these compounds with a given reagent vary with regard to the rate, thermometric, and even the completion of the reaction. Call chlorides, due to their reactivity, are good starting materials for synthesis.

Esters and amides are important functional groups in bimolecular like fats and proteins. All carboxylic acid derivatives yield the parent carboxylic acid upon reaction with water. Moreover, one derivative can be converted into another, provided the former is more reactive than the latter. II. Objectives To differentiate the reactivates of carboxylic acid derivatives. To distinguished carboxylic acid derivatives using classification tests To explain through chemical equations and mechanisms the reactions involved in each test. Ill.
