(D) The structure is $NC-CH_2-CH_2-CN$. The longest carbon chain contains $4$ carbon atoms. The functional group is nitrile $(-CN)$. Since the carbon of the nitrile group is included in the parent chain,the suffix used is 'nitrile'. The numbering starts from one of the nitrile carbons,giving the positions $1$ and $4$. Thus,the $IUPAC$ name is Butane $-1, 4-$ dinitrile.

Match List-$I$ with List-$II$.

List-$I$ (structure) List-$II$ ($IUPAC$ Name)

$A$. $CH_3CH_2CH(CH_2CH_3)CH_2CH(CH_3)CH_2CH_3$ $I$. $4-$Methylpent$-1-$ene

$B$. $(CH_3)_2C(C_3H_7)_2$ $II$. $3-$Ethyl$-5-$methylheptane

$C$. $CH_2=C(CH_3)CH=CHCH_3$ $III$. $4,4-$Dimethylheptane

$D$. $CH_2=CHCH_2CH(CH_3)CH_3$ $IV$. $2-$Methyl$-1,3-$pentadiene

Choose the correct answer from the options given below:

List-$I$ (structure)	List-$II$ ($IUPAC$ Name)
$A$. $CH_3CH_2CH(CH_2CH_3)CH_2CH(CH_3)CH_2CH_3$	$I$. $4-$Methylpent$-1-$ene
