Final answer:
The main focus of the lab experiment is to study the dehydration of alcohols.
Step-by-step explanation:
The main focus of the lab experiment on Methylcyclohexenes: Alcohol Dehydration is to study the dehydration of alcohols. In this experiment, an alcohol undergoes dehydration in the presence of a catalyst to form an alkene and water. The reaction removes the OH group from the alcohol carbon atom and a hydrogen atom from an adjacent carbon atom in the same molecule.
