The given structure is CH3-C≡C-C(CH3)2-C≡CH. It has two triple bonds and two methyl groups branching off the central carbon.
Step 2: Identify the longest carbon chain
The longest continuous carbon chain contains six carbons. Even though the triple bonds cause a linear geometry, the longest chain still includes the central carbon with its two methyl substituents.
Step 3: Name the compound
The parent chain with six carbons and two triple bonds is named hexa-2,4-diyne. The two methyl groups are on the same carbon (carbon 3). Therefore, the compound's name is 3,3-dimethylhexa-2,4-diyne.
