Identify the major product obtained when ethyl amine is reacted with excess of methyl iodide ?

Options

  1. ATetramethylammonium iodide
  2. BEthyltrimethylammonium iodide
  3. CEthyldimethylamine
  4. DEthylmethylamine

Correct answer

B. Ethyltrimethylammonium iodide

Step-by-step solution

Ethyl amine reacts with excess of methyl iodide to undergo exhaustive methylation, forming a quaternary ammonium salt. C₂H₅NH₂ + CH₃I C₂H₅NHCH₃ + HI C₂H₅NHCH₃ + CH₃I C₂H₅N(CH₃)₂ + HI C₂H₅N(CH₃)₂ + CH₃I [C₂H₅N(CH₃)₃]^+ I^- Since methyl iodide is in excess, the reaction does not stop at the secondary or tertiary amine stage but proceeds to the final quaternary ammonium salt. The major product obtained is ethyltrimethylammonium iodide. Answer: Ethyltrimethylammonium iodide
