Describe the conditions of the $\text{KMnO}_4$ used to convert but-2-ene into $\text{Y}$.
At room conditions, $24.0\,\text{cm}^3$ of gas is released when an excess of $\text{Na}$ is added to $0.001\,\text{mol}$ of $\text{Y}$. Assume that under room conditions $1\,\text{mol}$ of gas occupies $24.0\,\text{dm}^3$.\n\nDeduce a possible structure of $\text{Y}$. Explain your answer.
Deduce the number of carbon atoms in a molecule of $\text{Z}$ from Fig. 5.1. Show your working.
Deduce which halogen is present in $\text{Z}$ from Fig. 5.1. Explain your answer.
Further peaks occur at $m/e = 29$ and $m/e = 49$.\n\nSuggest the formulae of these fragments. Deduce the name of $\text{Z}$.\n\n$m/e = 29$\n\n$m/e = 49$\n\nname of $\text{Z}$
