Which one of the following compounds shows 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. We analyze the structure of each compound: 2-Methylhex-2-ene: CH₃-C(CH₃)=CH-CH₂-CH₂-CH₃ . The carbon at position 2 is bonded to two identical methyl groups, so it does not show geometrical isomerism. 4-Methylhex-2-ene: CH₃-CH=CH-CH(CH₃)-CH₂-CH₃ . The carbon at position 2 is bonded to a hydrogen and a methyl group. The carbon at position 3 is bonded to a hydrogen and a sec-butyl group. Since both car
