MCQ
In which reaction product is hydrocarbon ?
  • $RCOOK$ $\xrightarrow{{Electrolysis}}$
  • B
    $RCOOAg$ $\xrightarrow{{{I_2}/\Delta }}$
  • C
    $CH_3-CH_3$ $\xrightarrow{{C{l_2}/h{\text{v}}}}$
  • D
    $\begin{array}{*{20}{c}}
      {\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{H_3}} \\ 
      {\,\,\,\,\,\,|} \\ 
      {C{H_3} - C - Cl} \\ 
      {\,\,\,\,\,\,|} \\ 
      {\,\,\,\,\,\,\,\,\,\,\,\,C{H_3}} 
    \end{array}\xrightarrow{{{C_2}{H_5}OH}}$

Answer

Correct option: A.
$RCOOK$ $\xrightarrow{{Electrolysis}}$
a
The electrolysis of potassium salt of carboxylic acid gives hydrocarbon.

$2 RCOOK +2 H _2 O \stackrel{\text { Electrolyzis }}{\longrightarrow} R - R +2 CO _2+2 NaOH + H _2 \uparrow$

This reaction is known as Kolbe electrolysis.
