    An organic compound contains carbon, hydro- gen and oxygen. Its elemental analysis gave C, 38.71% and H, 9.67%. The empirical formula of the compound would be:

    A) \[C{{H}_{2}}O\]

    B)  CHO

    C) \[C{{H}_{4}}O\]

    D) \[C{{H}_{3}}O\]  

    Correct Answer: D

    Solution :

    \[C=\frac{38.7}{12}=3.22=\frac{3.22}{3.22}=1\] \[H=\frac{9.67}{1}=9.67=\frac{9.67}{3.22}=3\] \[O=\frac{51.63}{16}=3.22=\frac{3.22}{3.22}=1\] \[\therefore \]Empirical formula is \[C{{H}_{3}}O\]
