A) \[RCOOK~\xrightarrow[oxidation]{Electrolytic}\]
B) \[RCO{{O}^{-}}A{{g}^{+}}\xrightarrow{B{{r}_{2}}}\]
C) \[C{{H}_{3}}C{{H}_{3}}\xrightarrow[hv]{C{{l}_{2}}}\]
D) \[{{(C{{H}_{3}})}_{3}}CCl\ \xrightarrow{{{C}_{2}}{{H}_{5}}OH}\]
Correct Answer: A
Solution :
[a] \[2RCOOK\xrightarrow[oxidation]{Electrolytic}2{{\underset{Anode}{\mathop{RCOO}}\,}^{-}}+\underset{Cathode}{\mathop{2{{K}^{+}}}}\,\] At anode \[2RCO{{O}^{-}}\to 2RC{{OO}^{\bullet }}+2{{e}^{-}}\] \[2RCO{{O}^{\bullet }}\to R-R+2C{{O}_{2}}\] At cathode \[2{{K}^{+}}+2{{e}^{-}}\to 2K\] \[2K+{{H}_{2}}O\to 2KOH+{{H}_{2}}\uparrow \]
