    An ether solution of \[PhC{{H}_{3}}(I),\,PhN{{H}_{2}}(II)\]and \[PhOH(III)\] is extracted with aqueous\[NaOH\]. The ether layer will contain what compound(s) after the extraction?

    A)  Only III                

    B)  I + II

    C)  II + III                   

    D)  I + III

    Correct Answer: B

    Solution :

                     When ethernal solution of \[PhC{{H}_{3}}\] (I), \[PhN{{H}_{2}}\](II) \[PhOH\] (III) is extracted with aqueous\[NaOH\], only \[PhOH\] reacts with \[NaOH\] to form sodium phenoxide salt which layers separately whereas \[PhC{{H}_{3}}\] and \[PhN{{H}_{2}}\]cannot react with \[NaOH\] and lie in ethernal layer.
