Question: Which reaction is used to prepare amines from alkyl halides? (2020) 2020

Options:

Correct Answer: Nucleophilic substitution

Exam Year: 2020

Solution:

Amines can be prepared from alkyl halides through nucleophilic substitution reactions, where the halide is replaced by an amine group.

Which reaction is used to prepare amines from alkyl halides? (2020) 2020

Step 1: Identify the alkyl halide, which is a compound containing a carbon chain and a halogen (like Cl, Br, or I).
Step 2: Choose an amine, which is a compound that contains a nitrogen atom bonded to hydrogen or carbon.
Step 3: Understand that a nucleophilic substitution reaction occurs when the amine acts as a nucleophile, meaning it donates a pair of electrons.
Step 4: The nucleophile (amine) attacks the carbon atom of the alkyl halide, which is bonded to the halogen.
Step 5: The halogen leaves as a halide ion (like Cl-, Br-, or I-), and the amine group replaces it.
Step 6: The result is the formation of an amine from the alkyl halide.
