    What is the pH value M of \[{{p}_{2}}>{{p}_{3}}>{{p}_{1}}\]?

    A)  \[{{p}_{2}}>{{p}_{1}}>{{p}_{3}}\]                                            

    B)  \[\Delta G-ve,\Delta H+ve\]     

    C)  \[\Delta S+ve\]              

    D)         \[\Delta G+ve,\Delta H-ve\]

    Correct Answer: D

    Solution :

    \[C{{H}_{3}}-{{O}^{-}}N{{a}^{+}}+C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-Br\xrightarrow{{}}\] \[{{B}_{4}}C\] \[SiC\] \[S{{i}_{3}}{{N}_{4}}\] \[{{H}_{2}}S{{O}_{4}}\] \[0\]
