$1, 1-	ext{dichloro}-1-	ext{pentene}$

Vedclass · Answer

(A) Geometrical isomerism is shown by alkenes where each carbon atom of the double bond is attached to two different groups. For $1, 1-	ext{dichloro}-1-	ext{pentene}$ $(CH_2=C(Cl)-CH_2-CH_2-CH_3)$,the first carbon atom is attached to two identical hydrogen atoms. Since both groups on the first carbon are the same,it cannot exhibit geometrical isomerism. In the other options,both carbon atoms of the double bond are attached to two different groups,allowing for geometrical isomerism.
