Describe the observation when aqueous bromine is added to alkene $X$.
Draw the structures of $X$, $Y$ and $Z$, given that, when each is separately reacted with hot, concentrated, acidified manganate(VII) ions until the reaction finishes, the carbon-containing products are: $X$: $\text{CO}_2 + (\text{CH}_3)_2\text{CO}$ $Y$: $\text{CO}_2 + \text{CH}_3\text{CH}_2\text{CO}_2\text{H}$ $Z$: $\text{CH}_3\text{CO}_2\text{H}$
Deduce the molecular formula for $X$, $Y$ and $Z$.
Name the class of compound each of $V$ and $W$ belongs to, where $V$ is $\text{CH}_3(\text{CH}_2)_2\text{CH}_2\text{OH}$ and $W$ is $(\text{CH}_3)_3\text{COH$.
Write an equation showing how $V$ reacts with sodium metal.
Name a reagent that can distinguish $V$ from $W$. Describe the observations. Give the reagent, the result with $V$, and the result with $W$.
