    On heating calcium acetate and calcium formate, the product formed is [DPMT 1984; EAMCET 1985; MP PMT 1996, 92; KCET 1990; CPMT 1979, 82, 84; BIT 1992; RPET 2000]

    A)                 \[C{{H}_{3}}COC{{H}_{3}}\]        

    B)                 \[C{{H}_{3}}CHO\]

    C)                 \[HCHO+CaC{{O}_{3}}\]               

    D)                 \[C{{H}_{3}}CHO+CaC{{O}_{3}}\]

    Correct Answer: D

    Solution :

               \[\begin{matrix}    C{{H}_{3}}COO  \\    C{{H}_{3}}COO  \\ \end{matrix}>Ca+Ca<\begin{matrix}    OOCH  \\    OOCH  \\ \end{matrix}\xrightarrow{\text{Distill}}\]                                                                                 \[2C{{H}_{3}}CHO+2CaC{{O}_{3}}\]
