Question

Quizplus · Accepted Answer

In order to produce 2-methyl-3-pentene by dehydration, the alcohol used should have a methyl group attached to the carbon atom adjacent to the hydroxyl group (i.e. the carbon next to the –OH group). 
Out of the given options, only 4-methyl-2-pentanol satisfies this condition, as it has a methyl group attached to the second carbon atom from the –OH group. Hence, option B is the best choice.
