cetona

Also known as ketones

In organic chemistry, a ketone is an organic compound with the structure , where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond C=O). A ketone derived from an alkane is an alkanone. The simplest ketone is acetone (where R and R' are methyl), with the formula . Many ketones are of great importance in biology and industry. Examples include many sugars (ketoses), many steroids, e.g., testosterone, and the solvent acetone.

AI overview

A ketone is a type of organic compound built around a carbon-oxygen double bond, with carbon atoms attached on either side of that bond. Ketones are important because they appear widely in nature and industry—showing up in sugars, hormones like testosterone, and useful solvents like acetone.

Cetona é uma função química importante na química orgânica, caracterizados pela presença da ligação dupla carbono oxigênio ( C=O), chamado carbonila, ligado a dois radicais orgânicos. A fórmula geral das cetonas é R—C(=O)—R', R e R' podem ser radicais iguais (cetonas simples ou simétricas) ou diferentes (cetonas mistas ou assimétricas). Os radicais podem ser alifáticos ou aromáticos; saturados ou insaturados e R e R' podem também estar unidos, resultando em uma cetona cíclica. Se R ou R' é um átomo de hidrogênio, trata-se de um aldeído.
