Questions & Step-by-Step Solutions
What is the primary product of the reaction between 1-chlorobutane and potassium cyanide?
Correct Answer: 1-cyanobutane
Step 1: Identify the reactants. We have 1-chlorobutane, which is a four-carbon chain with a chlorine atom attached to the first carbon, and potassium cyanide, which provides the cyanide ion (CN-).
Step 2: Understand the type of reaction. This reaction is a nucleophilic substitution, where the cyanide ion will replace the chlorine atom in 1-chlorobutane.
Step 3: Recognize the nucleophile. The cyanide ion (CN-) is a strong nucleophile, meaning it is attracted to the positive part of the carbon atom that is bonded to chlorine.
Step 4: Perform the substitution. The cyanide ion attacks the carbon atom in 1-chlorobutane that is attached to the chlorine, leading to the displacement of the chlorine atom.
Step 5: Identify the product. After the substitution, the product formed is 1-cyanobutane, which has a cyanide group (CN) attached to the first carbon of the butane chain.
