could you please explain the nomenclature of alkynes?
The following rules summarize alkyne nomenclature.
Identify the longest continuous chain of carbon atoms that contains the carbon-carbon triple bond. The parent name of the alkyne comes from the IUPAC name for the alkane of the same number of carbon atoms, except the - ane ending is changed to - yne to signify the presence of a triple bond. Thus, if the longest continuous chain of carbon atoms containing a triple bond has five atoms, the compound is pentyne.
Number the carbon atoms of the longest continuous chain, starting at the end closest to the triple bond. Thus,
- The location and name of any substituent atom or group is indicated. For example, the compound
