Vedclass · Answer

(B) For a molecule to exhibit cis-trans (geometrical) isomerism,each carbon atom of the double bond must be attached to two different groups.In $CH_3-CH_2-CH=CH_2$,one carbon has two hydrogen atoms.In $ClCH=CHCl$,each carbon is attached to one $H$ atom and one $Cl$ atom. Since both carbons have different groups attached,it exhibits cis-trans isomerism.In $ClCH=CCl_2$,one carbon has two $Cl$ atoms.In $CH_2=CH-COOH$,one carbon has two $H$ atoms.Therefore,$ClCH=CHCl$ is the correct answer.
