What is the stability of a carboxylic acid derivative?
The stability of any type of carboxylic acid derivative is generally determined by the ability of its functional group to donate electrons to the rest of the molecule. In essence, the more electronegative the atom or group attached to carbonyl group, the less stable the molecule.
Which acid derivatives are most stable?
Acid chloride is the most reactive followed by acid anhydride, then ester and amide is the most stable acid derivative.
What are the 4 derivatives of carboxylic acids?
carboxylic acids
certain other groups are called carboxylic acid derivatives, the most important of which are acyl halides, acid anhydrides, esters, and amides.
Acyl chlorides are the most reactive carboxylic acid derivatives.
