    A mixture containing the following four compounds is extracted with 1M\[HCl\]. The compound that goes to aqueous layer is:
    (I)       
    (II)
    (III)
    (IV)

    A) (I)                   

    B) (II)  

    C) (III)                              

    D) (IV)

    Correct Answer: B

    Solution :

    [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 \[{{H}_{2}}O\] due to its charge. So, shaking with aqueous \[HCl\] will pull amines into the aqueous phase and leave all other compounds in organic layer.
