Question
An organic compound with molecular formula C₅H₁₀ shows geometrical isomerism but not chain isomerism with CH₃CH₂CH=CHCH₃. What is its structure?
Explanation
CH₃CH₂CH=CHCH₃ (pent-2-ene) shows geometrical isomerism (cis/trans) due to different substituents on the double bond. It has no chain isomerism with itself, as it’s the same structure.
