                   Which one of the following can be oxidised to the corresponding carbonyl compound?         

    A) 2-hydroxy-propane

    B) ortho-nitro ?phenol              

    C) Phenol                         

    D) 2-methyl-2-hydroxy-propane

    Correct Answer: A

    Solution :

    2-hydroxy propane or secondary alcohol is oxidised into propanone (correspondingcabonyl compound because in 2-hydroxypropane, secondary alcoholic group is present and it is oxidised into ketone). \[\text{CH3}\underset{2-hydroxy\,propane}{\mathop{\underset{\underset{\text{OH}}{\mathop{|}}\,}{\mathop{\text{CH}}}\,}}\,\text{C}{{\text{H}}_{\text{3}}}\xrightarrow{[\text{O}]}\text{ C}{{\text{H}}_{3}}\underset{\begin{smallmatrix} \Pr opane \\ (Keytone) \end{smallmatrix}}{\mathop{\underset{O}{\mathop{\underset{||}{\mathop{\text{C}}}\,}}\,}}\,\text{C}{{\text{H}}_{3}}\]
