    A compound contains 54.55 % carbon, 9.09% hydrogen, 36.36% oxygen. The empirical formula of this compound is:

    A) \[{{C}_{3}}{{H}_{5}}O\]                    

    B) \[{{C}_{4}}{{H}_{8}}{{O}_{2}}\]

    C) \[{{C}_{2}}{{H}_{4}}{{O}_{2}}\]                  

    D) \[{{C}_{2}}{{H}_{4}}O\]

    Correct Answer: D

    Solution :

    [d]
    C 54.55 54.55/12=4.5 4.5/2.27=2
    H 9.09 9.09/1-9.09 9.09/2.27=4
    O 36.36 36.36/16=2.27 2.27/2.27= 1
    Hence empirical formula of the compound \[={{C}_{2}}{{H}_{4}}O\]
