Which of the following alkenes is fundamentally incapable of exhibiting geometrical (cis-trans) isom — Hydrocarbons Chemistry Question

💡 Solution & Explanation

Geometrical isomerism requires that neither doubly bonded carbon atom holds two identical groups. In 2-methylpropene ($CH_2=C(CH_3)_2$), one carbon holds two identical methyl groups, and the other holds two hydrogens.
