Question

How many moles of methyl iodide are required to convert ethylamine into quaternary ammonium salt

Answer 1

In the first stage, a salt is formed - in this case, ethylammonium bromide a quaternary ammonium salt (one in which all four hydrogens

Answer 2

The number of methyl iodide molecules required to convert ethylamine into quarternary ammonium salt is equal to three.

• A quartenary ammonium salt is one in which all the hydrogen of the ammonium ions are replaced by alkyl groups.
• In etylamine there is already one hydrogen group of the ammonium group by ethyl ion.
• Hence three more methyl groups from three methyl iodide is required to convert etylamine into quarternary ammonium salt.
