Radial: A word with diverse meanings in medicine and the biomedical sciences: 1  Pertaining to the radius, the smaller bone in the forearm. 2  The radial artery is so named because of its proximity to the radius. 3  Pertaining to the radius of a circle.
A 3D model of ethyne (acetylene), the simplest alkyne. In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbonâcarbon triple bond. The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula CnH2nâ2.
Alkenes have less hydrogen atoms than alkanes. C 2 H 4 CH 2 =CH 2 C 3 H 6 CH 2 =CH-CH 3 Alkynes: an unsaturated hydrocarbon that contains one or more carbon-carbon triple bonds. The molecular formula of this group is C n H 2n-2 (n is the number of carbon atoms).r.
