Question

Quizplus · Accepted Answer

The given reaction is an acid-catalyzed dehydration of an alcohol. The H2SO4 protonates the alcohol group, leading to the formation of a good leaving group (H2O). The resulting carbocation can then lose a proton to form the double bond. Thus, the major organic product obtained from the given reaction would be II. Choice A (I) is incorrect because it is a starting material. Choice C (III) is incorrect because it is a rearranged product which can be formed under certain reaction conditions but is not the major product in this case. Choice D (IV) is incorrect because it is a side product formed due to over dehydration under harsh conditions.
