Question
- A. It acts as a leaving group
- B. It donates electrons to form a bond
- C. It stabilizes the intermediate
- D. It increases the steric hindrance
Answer
It donates electrons to form a bond
Explanation
The lone pair on nitrogen in amines acts as a nucleophile, donating electrons to form a bond with the electrophile during nucleophilic substitution reactions.
Common mistake
Incorrect Reaction Conditions
Students often forget to specify the necessary reaction conditions for the preparation of amines, such as the use of a reducing agent or specific temperature.
Always include the required reaction conditions when describing the preparation of amines. For example, state that amines can be prepared by reducing nitro compounds using lithium aluminium hydride (LiAlH4) under anhydrous conditions.
