Vedclass · Answer

(B) The reaction of the sodium salt of a carboxylic acid $(RCOONa)$ with soda lime $(NaOH + CaO)$ is known as decarboxylation. In this process,a molecule of $CO_2$ is removed as $Na_2CO_3$,resulting in an alkane with one carbon atom less than the starting carboxylic acid. The reaction is: $RCOONa + NaOH \xrightarrow{CaO, \Delta} R-H + Na_2CO_3$. Other options like Wurtz reaction $(R-X + Na)$ or Kolbe electrolysis increase the carbon chain length.
