Identify the starting material: The image shows a structure with a hydroxyl group (OH) attached to a carbon chain, indicating an alcohol. The problem mentions cis-1-heptene, which suggests the starting material is an alcohol that can form this alkene upon dehydration.
Understand the dehydration process: Dehydration of alcohols typically involves the removal of a water molecule (H2O) to form an alkene. This process often requires an acid catalyst and heat.
Determine the position of the double bond: In the dehydration of alcohols, the double bond forms between the carbon atoms adjacent to the hydroxyl group. The problem mentions cis-1-heptene, indicating the double bond is between the first and second carbon atoms.
Consider the stereochemistry: The term 'cis' refers to the configuration where the substituents on the double-bonded carbons are on the same side. This affects the naming of the alkene product.
Name the alkene product: Based on the position of the double bond and the stereochemistry, the alkene formed is named 1-heptene. The problem also mentions trans-1-heptene, which is the configuration where substituents are on opposite sides, but the correct answer is 1-heptene.
