In organic chemistry, an aldehyde (/ ˈældɪhaɪd /) is an organic compound containing a functional group with the structure R−CH=O. [1] . The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.

2025年1月22日 · aldehyde, any of a class of organic compounds in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom, and a single bond with another atom or group of atoms (designated R in general …

What are Aldehydes? Aldehydes are members of a class of organic chemical compounds represented by the general structural formula R-CHO. R may be hydrogen or a hydrocarbon radical–substituted or unsubstituted. Many aldehydes are volatile, flammable liquids which at normal room temperature form vapour in explosive concentrations.

2022年10月27日 · Identify the general structure for an aldehyde and a ketone. Use common names to name aldehydes and ketones. Use the IUPAC system to name aldehydes and ketones. The next functional group we consider, the carbonyl group, has a carbon-to-oxygen double bond.

An aldehyde is a common functional group in organic chemistry, and a class of organic compounds. In addition, they are primarily derivatives of alcohols. Aldehydes are responsible for natural and synthetic hormones. The structure of an aldehyde consists of a carbonyl group single bonded to a hydrogen atom.

Aldehydes and ketones are the simplest and most important carbonyl compounds. There are two systems of nomenclature of aldehydes and ketones. Aldehydes and ketones are often called by their common names instead of IUPAC names.

2023年1月23日 · This page explains what aldehydes and ketones are, and looks at the way their bonding affects their reactivity. It also considers their simple physical properties such as solubility and boiling points. Aldehydes and ketones are simple compounds which contain a carbonyl group - a carbon-oxygen double bond.

2022年7月26日 · Aldehydes and ketones are much alike in many of their reactions, owing to the presence of the carbonyl functional group in both. They differ greatly, however, in one most important type of reaction: oxidation. Aldehydes are readily oxidized to carboxylic acids, whereas ketones resist oxidation.

What are aldehydes and ketones? Aldehydes and ketones are simple compounds which contain a carbonyl group - a carbon-oxygen double bond.

Aldehydes are organic compounds characterized by the presence of a carbonyl group (C=O) attached to at least one hydrogen atom. Their general formula is R−CHO, where R can be a hydrogen atom (in the case of formaldehyde) or a hydrocarbon group (in other aldehydes like acetaldehyde or benzaldehyde).
