Write the chemical equation for the preparation of a primary amine from a primary alkyl halide.
Answer: RX + NH₃ (excess, alc., Δ, sealed tube) → RNH₂ (as RNH₃⁺X⁻, freed by base). Better: Gabriel phthalimide.
Solution
Ammonolysis:
(excess ammonia limits over-alkylation; the Gabriel phthalimide route gives the pure 1° amine).
(excess ammonia limits over-alkylation; the Gabriel phthalimide route gives the pure 1° amine).
