A) \[RCOOK\xrightarrow[oxidation]{Electrolytic}\]
B) \[RCO{{O}^{-}}A{{g}^{+}}\xrightarrow{B{{r}_{2}}}\]
C) \[C{{H}_{3}}C{{H}_{3}}\xrightarrow[h\upsilon ]{C{{l}_{2}}}\]
D) \[{{(C{{H}_{3}})}_{3}}CCl\xrightarrow{{{C}_{2}}{{H}_{5}}OH}\]
Correct Answer: A
Solution :
[a]| Electrolysis of a concentrated aqueous solution of either sodium or potassium salts of saturated mono-carboxylic aids yield higher alkane at anode |
| \[2RCOOK\xrightarrow[Oxidation]{Electrolytic}2{{\underset{Anode}{\mathop{RCOO}}\,}^{-}}+\underset{Cathode}{\mathop{2{{K}^{+}}}}\,\] |
| At anode |
| \[2RCO{{O}^{-}}\to 2RCOO+2{{e}^{-}}\xrightarrow{{}}R-R+2C{{O}_{2}}\] |
| At Cathode |
| \[2{{K}^{+}}+2{{e}^{-}}\xrightarrow{{}}2K\] |
| \[2K+{{H}_{2}}O\xrightarrow{{}}2KOH\underset{(Kolbe's\,\,method)}{\mathop{+{{H}_{2}}\uparrow }}\,\] |
