Explanation:

Step1: Analyze the naming rules

According to IUPAC (International Union of Pure and Applied Chemistry) naming rules for alkanes, when there are multiple substituents of the same type (here methyl groups), they should be named with a single prefix (di - for two in this case) and the locants (position numbers) should be listed in ascending order separated by commas.

Step2: Correct the name

The original name “2 - Methyl - 3 - methyl pentane” is incorrect. The correct way is to use the prefix “di -” for two methyl groups. The locants are 2 and 3. So the correct name is 2,3 - dimethylpentane.

Answer:

2,3 - dimethylpentane
