give the correct name for the following structure. use commas and hyphens where appropriate. remember that…

Explanation:

Step1: Identify the longest carbon - chain

The longest continuous carbon - chain has 9 carbon atoms, so the parent name is nonane.

Step2: Locate and name the substituents

There are 2 methyl groups ($-CH_3$). One is on the 2nd carbon and the other is on the 4th carbon.

Step3: Write the name

We list the substituents in alphabetical order (in this case, all are methyl groups), and indicate their positions with numbers separated by commas, and separate the numbers from the substituent name with a hyphen.

Answer:

2,4 - dimethylnonane
