In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) (lat. alcohol dehydrogenatum, [1] dehydrogenated alcohol)is an organic compound containing a functional group with the structure R−CH=O. [2]

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 chemical formulas and structure diagrams).

2021年5月25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.

Aldehyde- The aldehydes are a very important class of organic compounds; they are characterized by the presence of the formal functional group -CHO. The general formula of aldehyde can be written as R-CHO.

An aldehyde. Formaldehyde, which is the simplest aldehyde. An aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound. It contains a formyl group. A formyl group is a part of a molecule with the structure R-CHO. It is made of a carbon double bonded to oxygen. The carbon is also bonded to hydrogen and an R group. [1] A side chain is the rest ...

Aldehydes are defined as organic compounds that contain a functional group known as the aldehyde group, represented by the formula –CHO. In this structure, the carbon atom is double-bonded to an oxygen atom and single-bonded to a hydrogen atom …

2023年1月28日 · The carbon atom of this group has two remaining bonds that may be occupied by hydrogen, alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone.

2017年10月30日 · An aldehyde (RCHO) is a carbonyl compound where carbonyl group is bonded to one carbon (or alkyl group) and one hydrogen atom. The aldehydes are named from the name of corresponding longest carbon chain of aliphatic hydrocarbon containing the aldehyde group by replacing the ending -e with -al.

2022年7月26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.

aldehyde, Any of a class of organic compounds that contain a carbonyl group (―C=O; see functional group) in which the carbon atom is bonded to at least one hydrogen atom. Many have characteristic odours.
