Which shows an isomer of the molecule below?
blsea [12.9K]

Answer:

D.

Explanation:

Hello,

In this case, the isomer of an organic compound is another organic compound having the same molecular formula but different structural formula, thus, the given compound's molecular formula is C₅H₈ since it is an alkyne due to the triple bond. Next, we analyze each option:

A. C₅H₁₂

B. C₅H₁₀

C. C₅H₁₀

D. C₅H₈

For that reason answer is D. based on the molecular formula as well as due to the presence of the triple bond unsaturation (alkyne as well).

Best regards.
