The IUPAC name of the following compound is:

The correct answer is Option (3) → 2,6-Dimethylphenol

In the IUPAC system a hydroxy derivative of benzene is named as a phenol. The carbon carrying the –OH group is C-1, and the ring is numbered from it in the direction that gives the other substituents the lowest locants.

In the given compound both methyl groups are on the carbons next to the –OH group, one on each side. Counting from C-1 in either direction, they are on C-2 and C-6, so the name is 2,6-dimethylphenol.
