  • question_answer
    In the electrolysis of sodium acetate,\[{{H}_{2}}\]gas releases at cathode and\[{{C}_{2}}{{H}_{6}}\]gas at anode. This reaction is known as

    A)  Frenkland       

    B)  Kolbe

    C)  Clemmensen     

    D)  Wolff-Kishner

    Correct Answer: B

    Solution :

     Kolbe's electrolytic synthesis \[C{{H}_{3}}CO{{O}^{\text{O-}}}N{{a}^{\oplus }}C{{H}_{3}}CO{{O}^{\text{O-}}}+N{{a}^{\oplus }}\] at cathode \[N{{a}^{+}}+{{e}^{-}}\xrightarrow[{}]{{}}Na\] \[2Na+2{{H}_{2}}O\xrightarrow[{}]{{}}2NaOH+{{H}_{2}}\uparrow \] at anode \[C{{H}_{3}}CO{{O}^{-}}-2{{e}^{-}}\xrightarrow[{}]{{}}2C{{H}_{3}}COO\] \[2C{{H}_{3}}COO\xrightarrow[{}]{{}}{{C}_{2}}{{H}_{6}}+2C{{O}_{2}}\]
