Explanation:

The IUPAC nomenclature of alkanes are given as follows:

For any substituent attached, the numbering is done according to the priority of the functional group which is:-

Carboxylic Acids  > Acid Anhydrides   >  Esters    > Acyl Halides   > Amides   > Nitriles   >  Aldehydes    > Ketones   > Alcohols   > Thiols   > Amines   > Ethers   >  Sulphides   > Alkenes   > Alkynes   > Alkyl Halides   > Nitro   > Alkanes

Thus,

Numbering is shown below. The long chain is 6 membered ring having substituents ketone at C-2, methyl group at C-3 and chloro bond at C-5

The name is:-
