Question

What is the structure of the molecule named 3-hydroxy-4-isopropyltoluene?

Answer 1

The structure of 3-hydroxy-4-isopropyltoluene is

Explanation:

The methyl group of toluene is automatically assigned to `"C-1"`.

Then you count around the ring in any direction and put an `"OH"` group on `"C-3"`.

Continue around the ring and insert an isopropyl group on `"C-4"`.

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

`"OH"` has a higher priority than `"CH"_3`, so the official name of the compound is 2-isopropyl-5-methylphenol.
