Both carbonyl compounds and acid derivatives though they contain grouping yet the reactions given by them are entirely different.
As Aldehydes and Ketones give addition product with a nucleophile, while carboxylic acid derivatives give nucleophilic acyl substitution through addition/elimination mechanism.

Both carbonyl compounds and acid derivatives though they contain grouping yet the reactions given by them are entirely different. As Aldehydes and Ketones give addition product with a nucleophile, while carboxylic acid derivatives give nucleophilic acyl substitution through addition/elimination mechanism. Where X- = -Cl - O-overset(O)overset(||)C-R-OR, -NR(R) etc. Why aldeydes and Ketones give nucleophilic addition reaction while acid derivatives prefer nucleophilic acyl substititution reaction?

A : Aldehydes and ketones undergo nucleophilic addition reaction. R : Aldehydes and ketones contain carbonyl group.

Aldehyde, ketone, acid and acid derivatives contain gtC=O group. Aldehyde and ketones gives nucleop addition reactions where as acid and acid derivatives gives nucleophilic addition followed by ellmination reaction Nucleophilic addition reactions followed by ellimination of acid derivatives is known as acyl substitution reacts This subsitution reaction takes places by formation of tertrahedral intermediate.

For the given reaction which of these is correct?

Carboxylic acids contain carbonyl group but do not show the nucleophilic addition reactions like aldehydes or ketones. Why?

Aldehydes and ketones are amphoteric. Thus they can act both as acids and bases. Under acidic conditions, the carbon of the protonated canbonyl group is much more electrophilic, reacting even with weak nucleopphilie. Carbonyl compound gives nucleophilic addition reaction. In this reaction the nucleophilic attack proceeds the elecrophilic attack. Carbonyl compounds gives nucleophilic addition with

Statement-I: Unlike the gtC=O group of aldehydes and ketones, the C=O of R-overset(O)overset(||)C-OH does not undergo nucleophilic addition reactions. Because Statement-II: Carboxylic acids exist as dimers due to intermolecular hydrogen bonding in aprotic medium.
