Chemistry - Halogen Derivative Question with Solution | TestHub

Cresols are organic compounds that are methylphenols. They consist of a benzene ring substituted with one hydroxyl group ($-OH$) and one methyl group ($-C{H}_3$).

Since toluene is a benzene ring with a methyl group, adding a hydroxyl group makes it a hydroxytoluene.

Therefore, cresols are also known as hydroxytoluenes. There are three isomers: ortho-cresol, meta-cresol, and para-cresol.

Answer: Hydroxy toluenes.
