Ketone An organic compound containing

Kelvin scale A fundamental scale of temperature on which the triple point of water lies at 273.16 K and the lowest attainable temperature is at 0. The unit on the Kelvin scale is the kelvin, K. ketone An organic compound containing a carbonyl group between two carbon atoms, having the form R—CO R. Example CH3—CO—CH2CH , butanone. kilogram (kg) The SI unit of mass. See also Appendix IB.

Ketone ke- ton [Gr Keton, alter, of Aceton acetone] (1851) n. An organic compound containing a carbonyl group (C=0) bound to two carbon atoms. The simplest one is acetone (CH3)2C=0. It and the other lower ketones are widely used as solvents for vinyl and cellulosic resins, and as intermediates in the production of resins. Odian GC (2004) Principles of polymerization.

A cyanohydrin is an organic compound that contains both a cyanide and a hydroxy group on an aUphatic section of the molecule. Cyanohydrias are usually a-hydroxy nitriles which are the products of base-cataly2ed addition of hydrogen cyanide to the carbonyl group of aldehydes and ketones. The lUPAC name for cyanohydrias is based on the a-hydroxy nitrile name. Common names of cyanohydrias are derived from the aldehyde or ketoae from which they are formed (Table 1). 

Whereas aldehydes and ketones are one of the most important classes of organic compounds containing multiple bonds, no species with a E=0 double bond with E = Si, Ge, Sn, Pb could be isolated as a pure compound in the condensed phase148b 161. The ger-manone Tbt(Tip)Ge=0 116 prepared by Tokitoh s group could be detected in solution only. At room temperature, however, by insertion of the Ge=0 bond into a C—Si bond of an ortho-Bsi substituent of the employed Tbt ligand, it rearranges quickly to a mixture of diastereomeric benzogermacyclobutanes (equation 13)162.

A second reason for the vast number of organic compounds is that carbon atoms can form stable bonds with other elements. Several families of organic compounds (alcohols, aldehydes, ketones, esters, and ethers) contain oxygen atoms bonded to carbon. Others contain nitrogen, sulfur, or halogens. The presence of these elements confers a wide variety of new chemical and physical properties on an organic compound.

In addition to aldehydes and ketones, other organic molecules containing an electron-withdrawing functional group such esters, amides, nitriles, and nitro compounds can undergo aldol-like reactions as long as they contain a-hydrogen. Similarly, linear or branched alcohols can be synthesized by aldol condensation of short-chain linear alcohols (7,8).
