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,$l_1 < l_2$.

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