1) 1-butyne or but-1-yne 1. First found longest chain of 4 carbons. 2. But- is root for 4; -yne is suffix for alkyne. 3. The bottom blue numbering is used since it gives the lowest number to the triple bond, 1 . 4. So, put these pieces together and the name is the traditional name: 1-butyne or the new form: but-1-yne . 2) 2-butyne or but-2-yne 1. First found longest chain of 4 carbons. 2. But- is root for 4; -yne is suffix for alkyne. 3. Either numbering is fine since both ways would give the number, 2, to the triple bond. 4. So, put these pieces together to get the traditional name: 2-butyne or the new form: but-2-yne . 3) propyne 1. First found longest chain of 3 carbons. 2. Prop- is root for 3; -yne is suffix for alkyne. 3. The top red numbering is used since it gives the lowest number to the triple bond, 1 . 4. Since the triple bond can only be on carbon 1, the one can be omitted from the name giving us: propyne . 4) 4-nonyne or non-4-yne

1. First found longest chain of 9 carbons. 2. Non- is root for 9; -yne is suffix for alkyne. 3. The top red numbering is used since it gives the lowest number to the triple bond, 4 . 4. Put the pieces together, and the name should be complete with the traditional name: 4-nonyne or the new form: non-4-yne . 5) 5,5-dimethyl-1-hexyne or 5,5-dimethylhex-1-yne 1. First found longest chain of 6 carbons. 2. Hex- is root for 6; -yne is suffix for alkyne. 3. The right blue numbering is used since it gives the lowest number to the triple bond, 1 . 4. Then, the side chains were located: 5-methyl and 5-methyl . Since there are two methyls, the "di" prefix is added, and they are written as 5,5- dimethyl . 5. So, the final name must be the traditional name: 5,5-dimethyl-1-hexyne or the new form: 5,5-dimethylhex-1-yne . 6) 5-ethyl-5-methyl-3-octyne or 5-ethyl-5-methyloct-3-yne 1. First found longest chain of 8 carbons.
