Aldehyde structure. 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.
Common name for alcohol Common name for aldehyde Common name for acid Common name for ketone 1: Meth-Methyl alcohol (wood alcohol) Formaldehyde: Formic acid NA 2: Eth-Ethyl alcohol (grain alcohol) Acetaldehyde: Acetic acid (vinegar) NA 3: Prop-Propyl alcohol: Propionaldehyde: Propionic acid Acetone/dimethyl ketone 4: But-Butyl alcohol ...
An aldehyde is either a functional group consisting of a terminal carbonyl group, or a compound containing a terminal carbonyl group. (Where -R represents the carbon chain.) Subcategories
Glutaraldehyde is an organic compound with the formula (CH 2) 3 (CHO) 2.The molecule consists of a five carbon chain doubly terminated with formyl (CHO) groups. It is usually used as a solution in water, and such solutions exists as a collection of hydrates, cyclic derivatives, and condensation products, several of which interconvert.
Imines are related to ketones and aldehydes by replacement of the oxygen with an NR group. When R = H, the compound is a primary imine, when R is hydrocarbyl, the compound is a secondary imine. If this group is not a hydrogen atom, then the compound can sometimes be referred to as a Schiff base. [9]
An aldehyde differs from a ketone in that it has a hydrogen atom attached to its carbonyl group, making aldehydes easier to oxidize. Ketones do not have a hydrogen atom bonded to the carbonyl group, and are therefore more resistant to oxidation. They are oxidized only by powerful oxidizing agents which have the ability to cleave carbon–carbon ...
The name combines the suffix 'ol' from the alcohol and the prefix depending on the carbonyl group, either 'ald' for an aldehyde, or 'ket' for a ketone, in which case it referred to as a 'ketol'. An aldol may also use the term β-hydroxy aldehyde (or β-hydroxy ketone for a ketol). The term "aldol" may refer to 3-hydroxybutanal. [1] [2]
In organic chemistry, a hemiacetal is a functional group the general formula R 1 R 2 C(OH)OR, where R 1, R 2 is a hydrogen atom or an organic substituent. They generally result from the nucleophilic addition of an alcohol (a compound with at least one hydroxy group) to an aldehyde (R−CH=O) or a ketone (R 2 C=O) under acidic conditions.
