Question

compare alkyl nucleophilic substitution with acyl nucleophilic substitution
​

Answer 1

Answer:

Explanation:

Nucleophilic acyl substitution describe a class of substitution reactions involving nucleophiles and acyl compounds. In this type of reaction, a nucleophile – such as an alcohol, amine, or enolate – displaces the leaving group of an acyl derivative – such as an acid halide, anhydride, or ester.\

In alkyl halides, the carbon atom is sp3 hybridized whereas in aryl halides, it is sp2 hybridized and hence, more electronegative.

Answer 2

Answer:

The oxygen atom in the acyl group is double-bonded to the carbon atom, but there is no oxygen atom in the alkyl group. This is the primary difference between the alkyl and acyl groups.

Explanation:

• A class of substitution reactions involving nucleophiles and acyl compounds is referred to as nucleophilic acyl substitution.
• In this kind of reaction, the leaving group of an acyl derivative, such as an acid halide, anhydride, or ester, is replaced by a nucleophile such an alcohol, amine, or enolate.

• The carbon atom is sp3 hybridized in alkyl halides while it is sp2 hybridized and more electronegative in aryl halides.

• Is that aryl is any univalent organic radical created from an aromatic hydrocarbon by removing a hydrogen atom, while acyl is any of the class of organic radicals, rco-, created when a carboxylic acid's hydroxyl group is removed.
