The hydrocarbon $\text{C}_4\text{H}_8$ exists as two structural isomers, but-1-ene and but-2-ene. Which statement is correct?
- ABut-2-ene has the structural formula $\text{CH}_3\text{CH}={\text{CHCH}}_3$ and the same general formula as butane.
- BBut-2-ene has the structural formula $\text{CH}_3\text{CH}={\text{CHCH}}_3$ and the same empirical formula as ethene.
- CBut-1-ene has the structural formula $\text{CH}_3\text{CH}_2\text{CH}=\text{CH}_2$ and the same general formula as butane.
- DBut-1-ene has the structural formula $\text{CH}_3\text{CHCH}_2=\text{CH}$ and the same empirical formula as ethene.
