A) \[{{C}_{2}}{{H}_{6}}\]and\[C{{O}_{2}}\]
B) \[{{C}_{2}}{{H}_{4}}\]and\[C{{O}_{2}}\]
C) \[C{{H}_{4}}\]and\[{{H}_{2}}\]
D) \[C{{H}_{4}}\]and\[C{{O}_{2}}\]
Correct Answer: A
Solution :
This is an example of Kolbes electrolysis. \[2C{{H}_{3}}COOK\xrightarrow{electrolysis}2C{{H}_{3}}CO{{O}^{-}}+2{{K}^{+}}\] At cathode: \[2{{K}^{+}}+2{{e}^{-}}\xrightarrow{{}}2K\] \[2K+2{{H}_{2}}O\xrightarrow{{}}2KOH+{{H}_{2}}\uparrow \] At anode: \[2C{{H}_{3}}CO{{O}^{-}}\xrightarrow{{}}2\underset{\begin{align} & \downarrow -2C{{O}_{2}} \\ & 2C{{\overset{\centerdot }{\mathop{H}}\,}_{3}} \\ & \downarrow \\ & {{C}_{2}}{{H}_{6}} \\ \end{align}}{\mathop{C}}\,{{H}_{3}}CO\overset{\centerdot }{\mathop{O}}\,+2{{e}^{-}}\]You need to login to perform this action.
