a hydrocarbon with one or more triple bonds.
The general name for linear or branched aliphatic hydrocarbons that contain a triple bond. Aliphatic compounds can be represented by drawing the full structures as in Figure 2 or they can be written in an abbreviated form such as CH4 for methane (1) and CH3CH2CH3 for propane (3) (the main constituent of LPG). The abbreviated form will generally be used in this lecture. Sometimes aliphatic hydrocarbons will be drawn with only the carbon backbone. When this is done it is assumed that each carbon will have enough hydrogens attached (one, two or three) to make up its four bonds. For example: Cyclic aliphatic hydrocarbons are sometimes drawn with lines joining imaginary carbons. This is a very convenient way of drawing cyclic structures. Thus, cyclohexane (2) can be drawn as: It is assumed that there are two hydrogens at each corner of the cyclic shape unless otherwise indicated.
hydrocarbon containing a triple bond; often rather reactive.
A hydrocarbon that contains one or more carbon-to-carbon triple bonds.
An unsaturated aliphatic hydrocarbon characterised by the presence of a triple [C=C] bond. The generic formula for an alkyne is .... The most important member of this group is acetylene, HCCH, the first member of the series
an unsaturated hydrocarbon containing a carbon - carbon triple bond. The general formula is CnH2n22.
A compound that consists of only carbon and hydrogen, that contains at least one carbon-carbon triple bond. Alkyne names end with -yne. Examples are acetylene (CH CH); 1-propyne (CH2 CH2CH3), and 2-octyne (CH3CH2 CH2(CH2)4CH3).
A group of hydrocarbons with the general formula CnH(2n-2). Alkynes contain at least one carbon-carbon triple bond; common examples include ethyne also known as acetylene.
Alkynes are hydrocarbons that have at least one triple bond between two carbon atoms, with the formula CnH2n-2. The alkynes are traditionally known as acetylenes or the acetylene series, although the name acetylene is also used to refer specifically to the simplest member of the series, known as ethyne (C2H2) using formal IUPAC nomenclature.
