D) 4

Question

Quizplus · Accepted Answer

3-methyl-3-pentanol has a tertiary alcohol group that can undergo dehydration to form an alkene. The alkene formed will have a double bond in place of the alcohol group. Since there are two different hydrogen atoms on the carbon adjacent to the alcohol group, two different alkene products can be formed (cis and trans isomers). Therefore, the total number of products is 2.
