Reaction of bromoethane with alcoholic ammonia under pressure gives
- A. ethanol
- B. ethylamine
- C. ethanenitrile
- D. ethane
Explanation
Ammonia has a lone pair on nitrogen and acts as a nucleophile, displacing bromide to give ethylamine, though the product is itself nucleophilic so further substitution to secondary and tertiary amines readily follows. Using a large excess of ammonia limits this. Ethanenitrile would be formed with potassium cyanide instead.
