Vedclass · Answer

(A) The structure of $hexa-1, 3, 5-triene$ is $CH_2=CH-CH=CH-CH=CH_2$. Geometrical isomerism occurs due to restricted rotation around double bonds. In this molecule,there are $3$ double bonds. However,the terminal double bonds ($C_1=C_2$ and $C_5=C_6$) cannot exhibit geometrical isomerism because they are attached to two identical hydrogen atoms. Only the central double bond $(C_3=C_4)$ can exhibit geometrical isomerism ($cis$ and $trans$). Therefore,the total number of geometrical isomers is $2$ ($cis$ and $trans$).

The total number of geometrical isomers for the compound $hexa-1, 3, 5-triene$ is:
