MCQ
A mixture containing the following four compounds is extracted with $1 \,M\, HCl$. The compound that goes to aqueous layer is
- A$(I)$
- ✓$(II)$
- C$(III)$
- D$(IV)$
✓
Answer
Correct option: B.
$(II)$
b
when the given mixture is shaken with $1\, M HCl$, amine get protonated and becomes cation $\left( {RNH_2^ \oplus } \right)$ , which does not dissolve in organic solvent but usually dissolve in $H_2O$ due to its charge. So, shaking with aqueous $HCl$ will pull amines into the aqueous phase and leave all other compounds in organic layer
