Work Step by Step

These structures for alkynes are made according to the nomenclature system rules set by the IUPAC. 1. The base name indicates the number of carbon atoms present in the longest continuous carbon chain. In this case, Octyne indicates 8 Carbon atoms. Also, '-yne' indicates the presence of triple bonds in the structure. 2. The numbering of Carbon atoms starts from the left-hand side. 3. The triple bond is present between the carbon number 4 and 5. A carbon atom can form 4 bonds, therefore the hydrogen atoms are placed accordingly.
