Challenge Question$($s$)($expect to spend $1-2$ hrs on this portion of the assignment$)$

The following questions will be about forming solutions with $C{H}_2{O}_2$ and $C{H}_{2}SO$ as the solutes.

a$.$ Which solvent will dissolve both compounds, $C{H}_2{O}_2$ and $C{H}_{2}SO,$ forming a homogenous solution with each? Methanol or tetrachloromethane. Explain your answer using intermolecular forces.

Methanol:

Tetrachloromethane:

b$.$ Consider the solution made when $C{H}_{2}SO$ is combined with the solvent in your answer to question a$.$ Will the formation of the solution be endothermic, exothermic, or ideal. Explain your answer $($a calculation is not necessary$).$

c$.$ Consider the solution made when $C{H}_2{O}_2$ is combined with the solvent in your answer to question a$.$ Predict if the vapor pressure if the vapor pressure of the solution will be greater then, less then, or the same as the vapor pressure predicted by Raoult's law. Explain your answer. $($note: both the solute and solvent are volatile$)$
