From this list, identify all the chlorides that possess giant ionic structures in the solid state.
From this list, identify all the chlorides that react vigorously with water to produce strongly acidic solutions.
From this list, identify the chloride that dissolves in water to give a neutral solution.
From this list, identify the chloride formed from the element with the highest melting point.
$\text{NaCl}$ is one product of the reaction of chlorine gas and cold aqueous sodium hydroxide. Identify the other products.
$\text{PCl}_5$ reacts with alcohols to form chloroalkanes. Identify this type of reaction.
Draw the structure of the organic product formed in the reaction of an excess of $\text{PCl}_5$ with butane-1,3-diol.
Sulfur, $\text{S}_8$, reacts with chlorine to produce a range of chlorides. The main ones are $\text{S}_2\text{Cl}_2$ and $\text{SCl}_2$. $\text{SCl}_2$ is formed when sulfur reacts with excess chlorine. reaction 1: $\text{S}_8\text{(s)} + 4\text{Cl}_2\text{(g)} \rightarrow 4\text{S}_2\text{Cl}_2\text{(l)} \quad \Delta H_r = -58.2\,\text{kJ mol}^{-1}$ reaction 2: $\text{S}_2\text{Cl}_2\text{(l)} + \text{Cl}_2\text{(g)} \rightleftharpoons 2\text{SCl}_2\text{(l)} \quad \Delta H_r = -40.6\,\text{kJ mol}^{-1}$ $\text{SCl}_2$ is a cherry-red liquid that reacts vigorously with water to form an acidic solution. Use this information to deduce the bonding and structure shown by $\text{SCl}_2$. Explain your answer.
Calculate the enthalpy change of formation, $\Delta H_f$, of $\text{SCl}_2\text{(l)}$. You may find it useful to use Hess’s Law to construct an energy cycle. enthalpy change of formation of $\text{SCl}_2\text{(l)}$, $\Delta H_f = \ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\, \text{kJ mol}^{-1}$
