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

• C. $1-heptene$
• D. $trans-1-heptene$

Answer: (C)

Verified step by step guidance

1. Identify the starting compound: It is a primary alcohol with a seven-carbon chain (heptanol). The hydroxyl group (-OH) is attached to the first carbon.
2. Understand the reaction type: Dehydration of an alcohol using sulfuric acid (H\_2SO\_4) typically removes a water molecule (H\_2O) to form an alkene.
3. Determine the site of double bond formation: In primary alcohols, the double bond usually forms between the carbon bearing the -OH group and the adjacent carbon, resulting in an alkene at the 1-position.
4. Name the alkene product: Since the double bond is between carbon 1 and carbon 2 in a seven-carbon chain, the product is named 1-heptene.
5. Consider stereochemistry: For 1-heptene, cis/trans isomers are not applicable because the double bond is at the end of the chain (terminal alkene), so the product is simply 1-heptene.
