Answer
The name of the compound is $3,5-dimethylheptane$.
Work Step by Step
The compound has 7 carbon atoms in its longest continuous carbon chain ($hept-$) . It has 2 substituent, 2 methyl groups. The carbon chain is numbered so that the sum of the position of the substituents has the lowest numerical value. So, the 2 methyl substituents are at positions 3 and 5. Hence, the name of the compound is $3,5-dimethylheptane$.
