Quizplus · Accepted Answer

The reaction sequence involves a series of reactions of alkenes with different reagents. The first reaction (I) is an oxidative cleavage of the double bond in 2-methylpent-2-ene with hot KMnO4, which generates carboxylic acids as the products. The second reaction (II) is a hydration of 3-methylbut-1-ene with H2SO4 and water, which generates a secondary alcohol. The third reaction (III) is a halogenation of 2-methylpropene with Br2, which generates a vicinal dibromide. The fourth reaction (IV) is a hydrogenation of ethyne with H2 and Pd/C, which generates ethane. Therefore, the product of the reaction sequence is option D (IV).
