How would i go about naming the cyclo and the ketone? I'm not sure what takes priority :cry:

i believe you start at the cyclohexanone (= position 1) and have the lower number for methyls

so something like
2,5 dimethylcyclohexanone

This is correct.

Curiously no stereochemistry was provided in the OP's drawing. If so, then it would look like 2S,5R-dimethylcyclohexanone for a given diastereoisomer, or whichever corresponds to the actual molecule.

The priority rankings are as follows:

Carboxylic Acids and their derivatives (esters, amides, nitriles, etc.)

Aldehydes

Ketones

Alcohols

Amines

Aklenes / Alkynes

Anyone who actually does organic chemistry thinks very little about IUPAC. Interesting to be reminded of these things:P
