Determine the name of the alkene product formed in the following dehydration reaction.

• A. $1-methylcyclohexene$
• B. $4-methylcyclohexene$
• C. $2-methylcyclohexene$
• D. $3-methylcyclohexene$

Answer: (A)

Verified step by step guidance

1. Identify the starting material in the dehydration reaction. The image shows a cyclohexanol with a methyl group attached to the ring.
2. Understand that dehydration of alcohols involves the removal of a water molecule, which typically results in the formation of a double bond (alkene).
3. Determine the position where the double bond will form. In cyclohexanol, the hydroxyl group (OH) is removed along with a hydrogen atom from an adjacent carbon, leading to the formation of a double bond.
4. Consider the stability of the possible alkene products. The most stable alkene is usually the one with the most substituted double bond, following Zaitsev's rule.
5. Based on the structure, the double bond will form between the carbon with the hydroxyl group and the adjacent carbon with the methyl group, resulting in 1-methylcyclohexene.
