Are nitrile carboxylic acid derivatives?
Despite not containing an acyl group, nitriles are still considered carboxylic acid derivatives since on hydrolysis they form carboxylic acids. These are most commonly made via the conversion of a carboxylic acid to a primary amide, followed by dehydration.
Can nitriles be hydrolyzed to carboxylic acids?
Nitriles can be hydrolyzed to carboxylic acids in acidic aqueous solutions, and to carboxylate salts with base-catalyzed hydrolysis: In both cases, the transformation consists of two main parts; conversion of the nitrile to an amide and hydrolysis of the amide to the corresponding carboxylic acid.
How do you convert nitrile to carboxylic acid?
Nitriles can be converted to carboxylic acid with heating in sulfuric acid. During the reaction an amide intermediate is formed.
What is the hydrolysis product of a nitrile?
When nitriles are hydrolysed you can think of them reacting with water in two stages – first to produce an amide, and then the ammonium salt of a carboxylic acid. For example, ethanenitrile would end up as ammonium ethanoate going via ethanamide.
What are the carboxylic acid derivatives?
The functional groups at the heart of this chapter are called carboxylic acid derivatives: they include carboxylic acids themselves, carboxylates (deprotonated carboxylic acids), amides, esters, thioesters, and acyl phosphates.
What can nitriles be converted to?
Nitriles can be converted to amides. This reaction can be acid or base catalyzed. In the case of acid catalysis the nitrile becomes protonated.
What type of reaction is nitrile to carboxylic acid?
Converting the nitrile into a carboxylic acid This is described as hydrolysis.
What happens when nitriles undergo acid hydrolysis?
What happens when nitriles undergo acid hydrolysis? Under acidic conditions, instead of getting an ammonium salt, the carboxylic acid is formed. For example, Ethanenitrile on getting hydrolysed in hydrochloric acid gives ethanamide in the first step, while ethanoic acid and ammonium chloride in the second step.

How are carboxylic acid derivatives prepared?
Carboxylic acid derivatives are usually prepared by a condensation reaction wherein the carboxylic acid is reacted with the corresponding functional group (alcohol, amine, etc.) with the expulsion of a molecule of water….Carboxylic Acid Derivative
Can nitriles be oxidized?
In conclusion, this reaction is significant because it is the first time nitrile oxidation at any metal has been followed by intermolecular imido transfer to a substrate. This suggests that nitrile oxidation is a plausible route into reactive metal–imido compounds for amination or aziridination reactions.
