The structure of 3-hydroxy-4-isopropyltoluene is

#### Explanation:

The methyl group of toluene is automatically assigned to $\text{C-1}$.

Then you count around the ring in any direction and put an $\text{OH}$ group on $\text{C-3}$.

Continue around the ring and insert an isopropyl group on $\text{C-4}$.

And you have the structure of 3-hydroxy-4-isopropyltoluene, better known as thymol.

$\text{OH}$ has a higher priority than ${\text{CH}}_{3}$, so the official name of the compound is 2-isopropyl-5-methylphenol.
