Solution: NAMING ALKYNES Naming an alkyne is similar to naming an alkane with a few differences. Find the longest carbon chain and change the “ane” ending to “yne”. If there is a tie between longest chains, choose the chain that gives the _________ substituents. Number the chain from the end closest to the triple bond and provide a number for its location. Substituents will be named alphabetically and a number will accompany the location of their attachment. If more than one of a similar alkyl group is present then we must use numerical prefixes to describe the number of them.             __________ – 2         __________ – 3         __________ – 4         __________ – 5
