Which of the following exhibits geometrical isomerism?

Step-by-step solution

Geometrical isomerism occurs in alkenes when each carbon atom of the double bond is attached to two different groups. Let us examine the structures of the given compounds. For 1, 2-dibromopropene, the structure is CH₃-C(Br)=CHBr . The carbon at position 2 is attached to a methyl group and a bromine atom. The carbon at position 1 is attached to a hydrogen atom and a bromine atom. Since both carbons have two different groups attached, this compound exhibits geometrical isomerism (cis and trans forms). For 2-methylbut
