Heterocyclic Compounds

A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring. Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.

What is heterocyclic compound with example?

Heterocyclic compounds are cyclic compounds with the ring containing carbon and other element, the component being oxygen, nitrogen and sulfur. The simplest of the five membered heterocyclic compounds are pyrrole, furan and thiophene, each of which contains single heteroatoms.

What is heterocyclic compound and its classification?

Classification. The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings.

What is pyrrole ring?

pyrrole, any of a class of organic compounds of the heterocyclic series characterized by a ring structure composed of four carbon atoms and one nitrogen atom. The simplest member of the pyrrole family is pyrrole itself, a compound with molecular formula C4H5N.

What is nomenclature of heterocyclic compounds?

The name of the heterocyclic ring is chosen as the parent compound and the name of the fused ring is attached as a prefix. The prefix in such names has the ending ‘o’, i.e., benzo, naphtho and so on

Why heterocyclic compounds are aromatic?

Examples of Heterocyclic Aromatic Compounds.

For a compound (or ion) to be considered aromatic, the molecule must be cyclic, planar, and must have 4n + 2 electrons in a conjugated system of p orbitals (usually on sp2-hybridized atoms. This is known as Hückel’s rule.
