give the iupac name for the following compound:

Explanation:

Step1: Identify the parent chain

The parent chain is a cyclohexane as it is a six - membered ring.

Step2: Locate and name substituents

There are three substituents: two methyl groups ($-CH_3$) and one ethyl group ($-CH_2CH_3$). The numbering of the ring should start from the carbon with the ethyl group to give the lowest possible numbers to all substituents. The ethyl group is at carbon - 1, and the two methyl groups are at carbon - 3.

Step3: Write the IUPAC name

The substituents are written in alphabetical order. So the name is 1 - ethyl - 3,3 - dimethylcyclohexane.

Answer:

1 - ethyl - 3,3 - dimethylcyclohexane
