Question

different structures of heterocyclic compounds - three, four, five, six and ten membered rings with examples?​

Answer 1

Answer:

Few pyrazoles occur naturally; the compounds of this class are usually prepared by the reaction of hydrazines with 1,3-diketones. Many synthetic pyrazole compounds are of importance as dyes and medicinals. Among them are the fever-reducing analgesic aminopyrine, the anti-inflammatory drug phenylbutazone, used in treating arthritis, the yellow food colour and fibre dye tartrazine, and a series of dyes used as sensitizing agents in colour photography.
