(A) The molecular formula $C_7H_{16}$ represents heptane and its isomers.Chain isomers are compounds with the same molecular formula but different carbon skeletons.The possible chain isomers for $C_7H_{16}$ are:$1$. $n$-heptane$2$. $2$-methylhexane$3$. $3$-methylhexane$4$. $3$-ethylpentane$5$. $2,2$-dimethylpentane$6$. $2,3$-dimethylpentane$7$. $2,4$-dimethylpentane$8$. $3,3$-dimethylpentane$9$. $2,2,3$-trimethylbutaneThere are a total of $9$ chain isomers for $C_7H_{16}$.

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

The number of different chain isomers for $C_7H_{16}$ is . . . . . . .
