The hydrocarbon $$\(\mathrm{C}_{4} \mathrm{H}_{8}\)$$ has two structural isomers, but-1-ene and but-2-ene. Which statement is correct?
A.
But-2-ene has the structural formula \(\mathrm{CH}_{3} \mathrm{CH}=\mathrm{CHCH}_{3}\) and the same general formula as butane.
B.
But-2-ene has the structural formula \(\mathrm{CH}_{3} \mathrm{CH}=\mathrm{CHCH}_{3}\) and the same empirical formula as ethene.
C.
But-1-ene has the structural formula \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}=\mathrm{CH}_{2}\) and the same general formula as butane.
D.
But-1-ene has the structural formula \(\mathrm{CH}_{3} \mathrm{CHCH}_{2}=\mathrm{CH}\) and the same empirical formula as ethene.
