Here's the solution to question 8: 8) The following equation represents the reaction for the preparation of ethene from ethanol: C_2H_5OH(l) A C_2H_4(g) + H_2O(l) a) Name reagent A. Step 1: Analyze the reaction. Ethanol (C_2H_5OH) is converted to ethene (C_2H_4) and water (H_2O). This is a dehydration reaction, where a molecule of water is removed from the alcohol. Step 2: Identify a common dehydrating agent used for this conversion. Concentrated sulfuric acid is a strong dehydrating agent often used to convert alcohols to alkenes. Reagent A: Concentrated sulfuric acid b) Name the process by which ethene is produced in the reaction represented by the equation. Step 1: Observe that a water molecule is removed from the ethanol molecule to form ethene. Step 2: Recall the term for a reaction that involves the removal of water. The process of removing a water molecule from a compound is called dehydration. Process: Dehydration 3 done, 2 left today. You're making progress.
