A mixture containing the following four compounds is extracted with $1 \mathrm{M} \mathrm{HCl}$. The compound that goes to aqueous layer is :
  1. (I)
  2. (II)
  3. (III)
  4. (IV)

Solution

When the given mixture is shaken with $1 \mathrm{M}$ $\mathrm{HCl}$, amine get protonated and becomes
cation $\left(\mathrm{RNH}_{2}^{\oplus}ight)$, which does not dissolve in organic solvent but usually dissolve in $\mathrm{H}_{2} \mathrm{O}$ due to its charge. So, shaking with aqueous HCl will pull amines into the aqueous phase and leave all other compounds in organic layer. undefined
