An oxime is one in a class of chemical compounds with the general formula R₁R₂CNOH, where R₁ is an organic side chain and R₂ is either hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. A chemical compound is a chemical substance formed from two or more elements, with a fixed ratio determining the composition. ...

An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon. ...

Oximes can be formed by the action of hydroxylamine on aldehydes or ketones. The compound hydroxylamine is a nitrogen-containing base whose chemical formula is NH2OH, and is therefore a close relative of the compound ammonia. ... An aldehyde is either a functional group consisting of a terminal carbonyl group or a compound containing a terminal carbonyl group. ... A ketone is either the functional group characterized by a carbonyl group linked to two other carbon atoms or a compound that contains this functional group. ...

The term oxime dates to the 19th century, a condensation of the words oxygen and imide. Alternative meaning: Nineteenth Century (periodical) (18th century — 19th century — 20th century — more centuries) As a means of recording the passage of time, the 19th century was that century which lasted from 1801-1900 in the sense of the Gregorian calendar. ... General Name, Symbol, Number oxygen, O, 8 Chemical series Chalcogens Group, Period, Block 16, 2, p Appearance colorless Atomic mass 15. ... In organic chemistry, imide is a functional group consisting of two carboxylic acid groups (or one dicarboxylic acid) bound to a primary amine or ammonia. ...

Oximes can be synthesized by condensation of an aldehyde or a ketone with hydroxylamine. The condensation of aldehydes with hydroxylamine gives aldoxime, and ketoxime is produced from ketones and hydroxylamine. Generally, oximes are colorless crystals and do not dissolve into water easily. Therefore, oxime is used for the identification of ketone or aldehyde. The hydrolysis of oximes proceeds easily by heating in the presence of various inorganic acids, and the oximes decompose into the corresponding ketones or aldehydes, and hydroxylamines. The reduction of oximes by sodium amalgam or hydrogenation produces amines. The reduction of aldoximes gives both primary amines and secondary amines. A condensation reaction (also known as a dehydration reaction or dehydration synthesis when water is lost) is a chemical reaction in which two molecules or moieties react and become covalently bonded to one another by the concurrent loss of a small molecule, often water or methanol. ... Quartz crystal A crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions. ... Hydrolysis is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. ... An acid (from Arabic Azait meaning oil, often represented by the generic formula AH) is typically a water-soluble, sour-tasting chemical compound. ... In chemistry, sodium amalgam is an amalgam, or alloy of mercury, with sodium metal. ... Hydrogenation is a chemical reaction in which unsaturated bonds between carbon atoms are reduced by attachment of a hydrogen atom to each carbon. ... Ammonia Amines are organic compounds containing nitrogen as the key atom in the amine functional group. ... The most fundamental reactions in chemistry are the redox processes. ...

Oximes exists as two stereoisomers: a syn isomer and an anti isomer. Aldoximes, except for aromatic aldoximes, exist only as a syn isomer, while ketoximes can be separated almost completely and obtained as a syn isomer and an anti isomer. Generally oximes can be changed to the corresponding amide derivatives by treatment with various acids. This reaction is called Beckmann rearrangement. In this reaction, a hydroxyl group is exchanged with the group that is in the anti position of the hydroxyl group. The amide derivatives that are obtained by Beckmann rearrangement can be transformed into a carboxylic acid and an amine by hydrolysis. Beckmann rearrangement is used for the industrial synthesis of caprolactam, which is the material used to make nylon-6. Stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in space is different in each isomer. ... In chemistry, an aromatic molecule is one in which electrons are free to cycle around circular arrangements of atoms, which are alternately singly and doubly bonded to one another. ... In chemistry, the term amide has several meanings. ... In chemistry, the Beckmann rearrangement is the rearrangement of a ketoxime to the corresponding amide in concentrated sulfuric acid, phosphorus pentachloride or a few other catalysts. ... Hydroxide is a functional group consisting of oxygen and hydrogen: -O−H It has a charge of 1-. The term hydroxyl group is used when the functional group -OH is counted as a substituent of an organic compound. ... Structure of a carboxylic acid Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)-OH, usually written as COOH. In general, the salts and anions of carboxylic acids are called carboxylates. ... Caprolactam (C6H11ON) is the monomer used in the production of nylon 6. ... Nylon represents a family of synthetic polymers, a thermoplastic material, invented in 1935 by Wallace Carothers at DuPont. ...
