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:-

c. 5-chloro-3-methyl-2-hexanone

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
