What is the main product when 1-chloropropane is treated with aqueous KOH? (2019)
Step 1: Identify the starting compound, which is 1-chloropropane. This compound has a chlorine atom attached to the first carbon of a three-carbon chain.
Step 2: Understand that aqueous KOH (potassium hydroxide in water) is a strong base and can act as a nucleophile, meaning it can donate a pair of electrons to form a bond.
Step 3: Recognize that in this reaction, the hydroxide ion (OH-) from KOH will attack the carbon atom that has the chlorine atom attached to it.
Step 4: The chlorine atom will leave as a chloride ion (Cl-), and the hydroxide ion will take its place, forming a new bond with the carbon.
Step 5: The result of this substitution reaction is the formation of propan-1-ol, which is an alcohol with the hydroxyl group (-OH) attached to the first carbon.
