Question

Describe the following: (i) Acetylation (ii) Cannizzaro reaction (iii) Cross aldol condensation (iv) Decarboxylation

Answer 1

Answer:

The definition of the following are :

i) Acetylation - Acetylation is  basically a chemical reaction that is called ethanoylation in the IUPAC nomenclature in chemistry. It describes a reaction that introduces an acetyl functional group into a chemical compound.

ii) Cannizzaro Reaction - The Cannizzaro reaction, is a chemical reaction that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to give a primary alcohol and a carboxylic acid.

iii)  Cross Aldol Condensation -  Crossed aldol condensation is defined as when In the presence of a strong base, two different molecules of aldehyde or ketone combine to form a β-hydroxyaldehyde or a β-hydroxyketone.  This reaction is called as the aldol condensation.

iv) Decarboxylation -  Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide. Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.
