Isopropanol is prepared by reacting proplene (CH3CHCH2) with sulfuric acid, followed by treatment with water.(a) Show the sequence of steps leading to the product. What is the role of sulfuric acid?(b) Draw the structure of an alcohol that is an isomer of isopropanol.(c) Is isopropanol a chiral molecule?(d) What property of isopropanol makes it useful as rubbing alcohol?
Under conditions of acid catalysis, alkenes react with water to form alcohols. As in the case with hydrogen halides, the addition reaction in the formation of alcohols is also governed by Markovnikov"s rule.

Identify all compounds in the proceeding steps.
