Hydrocarbons Question 239
Question: Which one of the following reactions is expected to readily give a hydrocarbon product in good yields-
Options:
A) $ RCOOK~\xrightarrow[oxidation]{Electrolytic} $
B) $ RCO{O^{-}}A{g^{+}}\xrightarrow{Br_2} $
C) $ CH_3CH_3\xrightarrow[hv]{Cl_2} $
D) $ {{(CH_3)}_3}CCl\ \xrightarrow{C_2H_5OH} $
Show Answer
Answer:
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+2CO_2 $ At cathode $ 2{K^{+}}+2{e^{-}}\to 2K $
$ 2K+H_2O\to 2KOH+H_2\uparrow $
