Vedclass · Answer

(A) $i$. The conversion of $n$-butane to $2$-methylpropane is an example of isomerization,which is categorized under $C$. Isomerism.$ii$. The reaction $CH_4 + Cl_2 \xrightarrow{hv} CH_3Cl + HCl$ is a classic example of free radical substitution,which is $A$.$iii$. The reaction $R-COONa \xrightarrow{	ext{soda-lime}} R-H$ is the decarboxylation of sodium salts of carboxylic acids,which is $D$.$iv$. The reaction $R-X + Na \xrightarrow{	ext{Ether}} R-R$ is the Wurtz reaction,which is $B$.Therefore,the correct matching is $i-C, ii-A, iii-D, iv-B$.

Column-$I$	Column-$II$
$i$. $n$-Butane $\to 2$-methylpropane	$A$. Free radical substitution
$ii$. $CH_4 + Cl_2 \xrightarrow{hv} CH_3Cl + HCl$	$B$. Wurtz reaction
$iii$. $R-COONa \xrightarrow{\text{soda-lime}} R-H$	$C$. Isomerism
$iv$. $R-X + Na \xrightarrow{\text{Ether}} R-R$	$D$. Decarboxylation
