Vedclass · Answer

(B) The $IUPAC$ name $3-$oxo$-2-$methylhex$-4-$enal indicates the following features:$1$. The parent chain is a hexane chain ($6$ carbons) with an aldehyde group $(-CHO)$ at position $1$.$2$. There is a methyl group $(-CH_3)$ at position $2$.$3$. There is an oxo group $(=O)$ at position $3$.$4$. There is a double bond at position $4$ (between carbons $4$ and $5$).The structure is: $CH_3-CH=CH-C(=O)-CH(CH_3)-CHO$.Comparing this with the options,the structure is represented by option $B$.

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

Identify the structure representing $3-$oxo$-2-$methylhex$-4-$enal.
