How is ethyl amine prepared from methyl iodide?
Advertisements
उत्तर
Methyl iodide reacts with alcoholic solution of potassium cyanide (KCN) to give ethane nitrile (or methyl cyanide) as the major product with a small amount of potassium iodide.
Ethane nitrile (or methyl cyanide) on reduction with sodium and alcohol (Mendius reaction) forms ethyl amine.
