Vedclass · Answer

(A) Geometrical isomerism in alkenes like $2$-butene $(CH_3-CH=CH-CH_3)$ arises because the carbon-carbon double bond consists of a $\sigma$-bond and a $\pi$-bond. The presence of the $\pi$-bond prevents free rotation around the $C=C$ axis,resulting in restricted rotation. This restricted rotation allows for the existence of distinct spatial arrangements of atoms or groups attached to the double-bonded carbons,leading to $cis$ and $trans$ isomers.

$2$-Butene exhibits geometrical isomerism due to:
