The compounds which contain hydroxyl group as a functional group is referred to as alcohol.The general formula for alcohol is $C_n{H}_{2n+1}OH$. In IUPAC naming, we add the suffix ol with the word root.

It is classified as:

1. Primary alcohol: In which one alkyl group is attached to a carbon atom attached with a hydroxyl group.
2. Secondary alcohol: In this, two alkyl groups are attached.
3. Tertiary alcohol: In tertiary alcohol, three alkyl groups are attached.

Oxymercuration- demercuration reaction is most commonly used for the addition of hydroxyl group to a double bond of a cycloalkene ring. In this reaction, the cyclic mercurian ion will form with the help of the reagent mercury(II) acetate. That carbon- mercury bond will reduce in the presence of sodium borohydride, and that reaction is known as the demercuration reaction. Also, we can do this reaction by acid- Catalyzed hydration reaction, but in that acidic conditions are used, therefore, we will not use this mechanism for the reaction.

Hence, the reagent used in the reaction is $1.Hg{\left(OAC\right)}_2,H_{2}O2.NaB{H}_4$:
