It is to be proposed how to carry out the given synthesis, in which an amide isconverted into an acid anhydride. Concept introduction: An acyl substitution that converts an acid derivative from a higher rung onthe stability ladder to one on a lower rung of the ladder is energeticallyfavorable. Therefore, the conversion of the more stable acid derivative to a less stable acid derivative is cannot proceeds in a single step. Thus for the conversion of an amide to an acid anhydride first amide must be converted to acid chloride. Amide on base hydrolysis produces corresponding carboxylic acid . Carboxylic acid on treatment either PCl 3 or SOCl 2 corresponding acid chloride is formed.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Using the conditions of spontaneity to deduce the signs of AH and AS Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions A This reaction is always spontaneous, but proceeds slower at temperatures above 120. °C.
