    The end product C in the following sequence of chemical reactions is \[C{{H}_{3}}COOH\xrightarrow[{}]{CaC{{O}_{3}}}A\xrightarrow[{}]{heat}B\xrightarrow[{}]{N{{H}_{2}}OH}C\]

    A)  acetaldehyde oxime     

    B)  formaldehyde oxime    

    C)  methyl nitrate

    D)  acetoxime

    Correct Answer: D

    Solution :

     \[C{{H}_{3}}COOH\xrightarrow[{}]{CaC{{O}_{3}}}\underset{A}{\mathop{{{(C{{H}_{3}}COO)}_{2}}Ca}}\,\] \[\xrightarrow[-CaC{{O}_{3}}]{\Delta }{{(C{{H}_{3}})}_{2}}CO\xrightarrow[-{{H}_{2}}O]{N{{H}_{2}}OH}\underset{acetoxime}{\mathop{{{(C{{H}_{3}})}_{2}}C=NOH}}\,\]
