The examples cover scenarios of numbering the parent chain by giving the triple bond the lowest priority when there is a tie as well as the Alkene Alkyne naming priority when there is a double and triple bond in the molecule. So, remember, we distinguish two units; the “main part” of the molecule, called the parent chain, and the additional group(s) known as substituents: The substituent can be a carbon fragment, and these are called alkyl groups, or any other functional group such as a halide, an OH, a nitro group etc. Displaying top 8 worksheets found for - Iupac Nomenclature Practice.

In this case, we have a methyl and an ethyl group. To do this, start numbering from the carbon directly connected to the actual parent chain of the molecule and list the alkyl groups alphabetically: Notice that at the end, the quasi parent chain gets the -yl suffix since it is still a substituent and the actual parent chain is placed at the end. No sign or space needed to separate two words. Question 1 The aim of the present document, prepared with the help of a panel of experts, is a revision of the recommendations in the light of new developments and current practice.
