Which of the following will show geometrical isomerism?

Step-by-step solution

Geometrical isomerism is exhibited by alkenes if both carbon atoms of the double bond are attached to two different groups. For 2-methylbut-2-ene, the structure is CH₃-C(CH₃)=CH-CH₃ . One carbon of the double bond is attached to two identical methyl groups, so it does not show geometrical isomerism. For 1,2-dibromopropene, the structure is CH₃-C(Br)=CH-Br . The first carbon is attached to a methyl group and a bromine atom, while the second carbon is attached to a hydrogen atom and a bromine atom. Since both carbons
