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 …

In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) 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 .

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8月10日 · The difference between aldehydes and ketones is the placement of the carbonyl group within the molecule. An aldehyde is an organic compound in which the carbonyl group is attached to a carbon atom at the end of a carbon chain. A ketone is an organic compound in which the carbonyl group is attached to a carbon atom within the carbon chain. The ...

2022年10月27日 · In an aldehyde, at least one of the attached groups must be a hydrogen atom. The following compounds are aldehydes: In condensed formulas, we use CHO to identify an aldehyde rather than COH, which might be confused with an alcohol.

2017年10月30日 · An aldehyde (RCHO) or alkanal is a carbonyl compound (compounds contain -CO- as a functional group) where carbonyl group is bonded to one carbon (or alkyl group) and one hydrogen atom. Ethanal is an example of aldheyde where one methyl group and one hydrogen group is added to the carbonyl carbon.

An aldehyde is an organic compound containing a terminal carbonyl group. This functional group, called an aldehyde group, consists of a carbon atom bonded to a hydrogen atom with a single covalent bond and an oxygen atom with a double bond.

2024年4月22日 · Aldehydes are organic compounds that have the functional group -CHO (formyl), a carbonyl group >C=O with a hydrogen. Aldehydes are present in many natural products and are widely used for the manufacture of all kinds of chemical compounds. For example, they have applications in materials such as plastics, perfumes, solvents, paints, resins, etc.

An aldehyde is an organic compound containing a terminal carbonyl group. This functional group, which consists of a carbon atom which is bonded to a hydrogen atom and double-bonded to an oxygen atom (chemical formula O=CH-), is called the aldehyde group. The aldehyde group is also called the formyl or methanoyl group.

Aldehydes are organic compounds characterized by the presence of a carbonyl group (-C=O) at the terminal carbon, which is also bonded to a hydrogen atom. This unique structural feature distinguishes aldehydes from other functional groups, such as …
