    Which of the following is least soluble in water?

    A)  HCHO       

    B)  \[C{{H}_{3}}CHO\]

    C)  \[C{{H}_{3}}COC{{H}_{3}}\]    

    D)  \[{{C}_{6}}{{H}_{5}}COC{{H}_{3}}\]

    Correct Answer: D

    Solution :

     Due to large hydrocarbon part, the extent of H-bonding between the polar carbonyl group and water molecules is least in\[{{C}_{6}}{{H}_{5}}COC{{H}_{3}}\] and hence, it is least soluble in\[{{H}_{2}}O\].
