Question

Which of the following is not a structural isomer of $C_5{H}_{10}$ ?

• A. Pent-1-ene
• B. 2-methylbut-2-ene
• C. 3-methylbut-1-ene
• D. 2,3 -dimethylpropene

Answer 1

Answer: (D)

Possible structural isomers of $C_5{H}_{10}$ are :


Hence, 2, 3-dimethylpropene is not a structural isomer of $C_5{H}_{10}$.
