Vedclass · Answer

(C) In a cumulative diene or polyene system like butatriene $(H_2C=C=C=CH_2)$,the terminal carbon atoms are $sp^2$ hybridized. Due to the nature of the $\pi$-bonds,the terminal $CH_2$ groups lie in perpendicular planes. Let the first $CH_2$ group be in the $xy$-plane. Then the second $CH_2$ group will be in the $xz$-plane. In the provided diagram,$l_1$ represents the distance between hydrogens in the same plane,while $l_2$ represents the distance between hydrogens in perpendicular planes. By geometry,the distance between atoms in perpendicular planes $(l_2)$ is greater than the distance between atoms in the same plane $(l_1)$. Therefore,$l_1 < l_2$.

List-$I$ (Pair of Compounds)	List-$II$ (Type of Isomers)
$A$. $2-$Methylpropene and but$-1-$ene	$I$. Stereoisomers
$B$. $Cis-$but$-2-$ene and $trans-$but$-2-$ene	$II$. Position isomers
$C$. $2-$Butanol and diethyl ether	$III$. Chain isomers
$D$. But$-1-$ene and but$-2-$ene	$IV$. Functional group isomers

Choose the correct relation between $l_1$ and $l_2$ for the given allene derivative (butatriene system):
