Answer the question on basis of passage given below:

Alcohols and phenol are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by -OH group. The substitution of a hydrogen atom in a hydrocarbon by an alkoxy or aryloxy group forms ethers.

Alcohols and phenol consist of two part, an alkyl/aryl group and a hydroxyl group. The properties of alcohols and phenols are primarily due to the hydroxyl group. The nature of alkyl and aryl groups simply modify these properties. Alcohol react both as nucleophiles and electrophiles whereas in phenols, the reactions that take place on the aromatic ring are electrophilic subtitution reactions.

The IUAC name of the following compound is:

2-Phenylpropan-2-ol

The correct answer is option 3. 2-Phenylpropan-2-ol.

Longest chain has 3 carbon atoms, so parent chain is propane. \(C_2\) contains an \(-OH\) group and a phenyl group. Thus, the name of the compound is 2-Phenylpropan-2-ol.
