Aldehydes are named by IUPAC nomenclature by changing the suffix -e of the parent alkane to -al. Aliphatic aldehydes are named as derivatives of their longest alkyl chain. Thus, HCHO is named as a derivative of methane, and CH3CH2CH2CHO is named as a derivative of butane. The suffix -al replaces the -e of the alkane name. Thus, HCHO is named methanal, more commonly known as formaldehyde, and CH3CH2 ...

Aldehydes (R-CHO) take the suffix "-al". Since they are always at the end of a alkane chain, they do not need a position number: HCHO (formaldehyde) is methanal, CH3CHO (acetaldehyde) is ethanal. If other functional groups are present, the chain is numbered such that the aldehyde carbon is in the "1" position. If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH3COOH is 3-oxopropanoic acid. If the carbon in the carbonyl group cannot be includ ...

The anticonvulsants, sometimes also called antiepileptics, belong to a diverse group of pharmaceuticals used in prevention of the occurrence of epileptic seizures. The goal of an anticonvulsant is to suppress the rapid and excessive firing of neurons that start a seizure. Failing this, a good anticonvulsant would prevent the spread of the seizure within the brain and offer protection against excitotoxic effects that can result in brain damage. An excellent anticonvulsant would have fe ...

An ylide is a neutral molecule with positive and negative charges on adjacent atoms. The most common ylides are phosphonium ylides, used in the Wittig reaction for double bond synthesis from carbonyl groups (C=O). The positive charge in these Wittig reagents is carried by a phosphorus atom with three phenyl substituents and one bond to a carbon bearing a negative charge and two substituents, commonly alkyl groups. Ylides can be 'stabilised' or 'non-stabilised'. Non-stabilised ylides react readily with both aldehydes and ketones wherea ...

Alcohol dehydrogenases are a group of dehydrogenase enzymes that occur in many organisms and facilitate the conversion between alcohols and aldehydes or ketones. In humans and many other animals, they serve to break down alcohols which could otherwise be toxic; in yeast and many bacteria they catalyze the opposite reaction as part of fermentation. The EC number of alcohol dehydrogenases is EC 1.1.1.1; their CAS number is 9031-72-5. Alcohol dehydrogenase - In humans. In humans, the enzyme is contained ...

In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom. The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex (e.g., nickel carbonyl); in this situation, carbon is triple-bonded to oxygen. A carbonyl group characterizes the following types of compounds (where -CO denotes a C=O carbonyl group): aldehyde- (R-CHO) ketone- (R-CO-R1) carboxylic acid- (R-COOH) ester- (R ...

The diamminesilver(I) complex is an oxidizing agent, which is itself reduced to silver metal, which in a clean glass reaction vessel forms a "silver mirror". This feature is used as a test for aldehydes, which are oxidised to carboxylic acids. Once it has been identified that there is a carbonyl group on the organic molecule using 2,4-dinitrophenylhydrazine (also known as Brady's reagent), Tollens' reagent can be used to ascertain whether the compound is a ketone or an aldehyde. When adding the aldehyde or ketone to Tollens' rea ...
