    The empirical formula of an acid is \[C{{H}_{2}}{{O}_{2}}\], the probable molecular formula of acid may be                    [AFMC 2000]

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

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

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

    D)                 \[{{C}_{3}}{{H}_{6}}{{O}_{4}}\]

    Correct Answer: B

    Solution :

     Empirical formula of an acid is \[C{{H}_{2}}{{O}_{2}}\]                    \[{{(\text{Empirical formula)}}_{n}}=\]Molecular formula                    n = whole no. multiple i.e. 1,2,3,4..............                                 If \[n=1\]molecular formula \[C{{H}_{2}}{{O}_{2}}\].
