What type of reaction occurs when 1-chloropropane reacts with aqueous KOH? (2023)

What type of reaction occurs when 1-chloropropane reacts with aqueous KOH? (2023)

Step 1: Identify the reactants. We have 1-chloropropane (a molecule with a chlorine atom) and aqueous KOH (potassium hydroxide in water).
Step 2: Understand what KOH does. KOH is a strong base that can remove hydrogen atoms from molecules.
Step 3: Recognize the type of reaction. When 1-chloropropane reacts with KOH, it can either substitute the chlorine or eliminate it.
Step 4: Determine the conditions. Since KOH is in water (aqueous), it favors elimination reactions over substitution.
Step 5: Identify the product. The elimination of HCl (hydrochloric acid) occurs, resulting in the formation of propene (an alkene).
Step 6: Conclude the reaction type. Therefore, the reaction is an elimination reaction.
