Which of the following compounds will show 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 2-methylbut-2-ene, the structure is CH₃-C(CH₃)=CH-CH₃ . The carbon at position 2 is attached to two identical methyl groups. Therefore, it does not show geometrical isomerism. For 1,2-dibromopropene, the structure is CH₃-C(Br)=CH-Br . The carbon at position 2 is attached to a methyl group and a bromine atom, which are different. The carbon at
