Two compounds, P and Q, both have the molecular formula C₄H₈. (a) Identify the type of isomerism between but-1-ene and but-2-ene. [1] (b) Explain why but-2-ene can exist as geometric isomers but but-1-ene cannot. [1]
Identify the pair of compounds shown in Diagram C.
Two compounds, P and Q, have the molecular formula $C_4H_8$. Compound P has the structure $\text{CH}_2=\text{CH}–\text{CH}_2–\text{CH}_3$, and compound Q has the structure $\text{(CH}_3\text{)}_2\text{C=CH}_2$. Which statement correctly identifies the relationship between P and Q?
