The sulfonation of p-cymene (l-methyl-4-isopropylbenzene) gives the 2-sulfonic acid. Is this the expected orientation Explain. Use this fact to synthesize carvacrol, 2-methyl-5-isopropylphenol, from p-cymene. Carvacrol is found in the essential oils from thyme, marjoram, and summer savory. It has a pleasant thymol-like odor.
