    Which one of the following can be oxidised to the corresponding carbonyl compound? [AIPMT (S) 2004]

    A) 2-hydroxy-propane         

    B) ortho-nitro -phenol         

    C) Phenol

    D)      2-methyl-2-hydroxy-propane

    Correct Answer: A

    Solution :

    [a] 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).
    \[\text{CH3}\underset{2-hydroxy\,propane}{\mathop{\underset{\underset{\text{OH}}{\mathop{|}}\,}{\mathop{\text{CH}}}\,}}\,\text{C}{{\text{H}}_{\text{3}}}\xrightarrow{[\text{O}]}\text{ C}{{\text{H}}_{3}}\underset{\begin{smallmatrix}  \Pr opane \\  (Keytone) \end{smallmatrix}}{\mathop{\underset{O}{\mathop{\underset{||}{\mathop{\text{C}}}\,}}\,}}\,\text{C}{{\text{H}}_{3}}\]
