Official Solution

Correct Option: (1)

The hydration of alkenes under acidic conditions typically follows Markovnikov's rule, where the hydrogen from the water adds to the less substituted carbon, while the OH group attaches to the more substituted carbon. Below is the detailed matching of the given alkenes and their corresponding products: List-I (Reactants) List-II (Products) (A) Propene (I) Isopropanol (B) 2-Methylpropene (III) 2-Methyl-2-propanol (C) 1-Butene (II) 2-Butanol (D) 2-Butene (IV) 2-Butanol By understanding the application of Markovnikov's rule and examining each of the given reactions, we can correctly match the reactants to their corresponding products: Propene, when hydrated, produces Isopropanol. Thus, (A) matches with (I). 2-Methylpropene reacts to form 2-Methyl-2-propanol, so (B) matches with (III). 1-Butene yields 2-Butanol due to rearrangement fitting Markovnikov's product, matching (C) with (II). 2-Butene also gives 2-Butanol indicating that (D) matches with (IV). Hence, the correct answer is (A) - (I), (B) - (III), (C) - (II), (D) - (IV).
