  • question_answer
    A compound (80 g) on analysis gave C = 24 g, H = 4 g,   O = 32 g. Its empirical formula is  

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

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

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

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

    Correct Answer: D

    Solution :

    \[C=24gm\], \[H=4gm\], \[O=32gm\]
                So, Molecular formula \[={{C}_{2}}{{H}_{4}}{{O}_{2}}\]
                So, Empirical formula \[=C{{H}_{2}}O\]
                            (Simplest formula).
