    Consider the following reactions, I. \[{{H}_{3}}CC{{l}_{3}}\xrightarrow{O{{H}^{\Theta }}}\] II. \[{{H}_{3}}CCHO\xrightarrow{{{[Ag{{(N{{H}_{3}})}_{2}}]}^{+}}O{{H}^{\Theta }}}\] III. \[{{H}_{3}}CC{{O}_{2}}{{C}_{2}}{{H}_{5}}\xrightarrow{O{{H}^{\Theta }}}\] Carboxylic acid is the final product only in the reaction (s)

    A)  I, II                                        

    B)  II, III

    C)  II                           

    D)  III

    Correct Answer: B

    Solution :

                     From ethylene (Wacker process)\[{{H}_{2}}C=C{{H}_{2}}+{{O}_{2}}\xrightarrow[{{H}_{2}}O]{PdC{{l}_{2}}\,.\,\,CuC{{l}_{2}}}{{H}_{3}}C-CHO\]\[-Pd\,;\,-2HCl\]
