Answer 2

Answer:

The area of organic chemistry that deals with the synthesis, characteristics, and uses of these heterocycles is known as heterocyclic chemistry. All of the nucleic acids, the bulk of pharmaceuticals, the majority of biomass (cellulose and related materials), and several natural and manmade colors are examples of heterocyclic compounds.

Explanation:

Six electrons are shared by five atoms in a five-membered ring; each atom has more than one share.

Such 5-membered rings are called excessive heterocycle.

Pyrrol, indole is a highly reactive excessive heterocycle that combines with halogens and other electrophiles very quickly. Nature has taken advantage of this characteristic to synthesize more than 300 halogenated indoles, mostly bromoindoles in marine organisms.

Hence, the correct answer is excessive heterocycle.
