Question

Rank the alcohols in order of increasing reactivity when dehydrated with H₂SO₄,putting the least reactive first. A)I < III < II B)I < II < III C)II < III < I D)III < II < I

Quizplus · Accepted Answer

The reactivity of alcohols in dehydration follows the order of tertiary > secondary > primary > methyl. Among the given alcohols, I is a primary alcohol, II is a secondary alcohol, and III is a tertiary alcohol. Thus, the least reactive alcohol is I, followed by III and then II. Therefore, the correct order of increasing reactivity is I < III < II, which is given in choice A.
