What type of reaction occurs when 1-chlorobutane is treated with aqueous KOH? (2023)

Step 1: Identify the reactant, which is 1-chlorobutane. It is a molecule that contains a chlorine atom attached to a four-carbon chain.
Step 2: Identify the reagent, which is aqueous KOH. This means potassium hydroxide is dissolved in water.
Step 3: Understand that KOH is a strong base and can act as a nucleophile, meaning it can donate a pair of electrons to form a bond.
Step 4: Recognize that in this reaction, the chlorine atom in 1-chlorobutane will be replaced by a hydroxyl group (OH) from KOH.
Step 5: This process is called nucleophilic substitution because the nucleophile (OH-) replaces the leaving group (Cl-).
Step 6: The product of this reaction is butanol, which is an alcohol with the hydroxyl group attached to the butane chain.
