    An oxygen containing organic compound upon oxidation forms a carboxylic acid as the only organic product with its molecular mass higher by 14 units. The organic compound is

    A)  an aldehyde

    B)  a primary alcohol

    C)  a secondary alcohol

    D)  a ketone

    Correct Answer: B

    Solution :

    Because the difference in mass between \[-C{{H}_{2}}OH\] group and \[-COOH\]group is 14, thus the compound which undergoes oxidation is a primary alcohol. (\[-C{{H}_{2}}OH\] is the functional group of primary alcohols.) \[\underset{primary\,alcohol}{\mathop{\underset{(R+31)}{\mathop{RC{{H}_{2}}OH}}\,}}\,\xrightarrow{[O]}\underset{acid}{\mathop{\underset{(R+45)}{\mathop{RCOOH}}\,}}\,\]
