Hydrogen Chloride (HCl) and methanol (CH3OH) will dissolve in water. The rest won't.

The only soluble substances are
a) HCl + H2O --------------> H3O+ + Cl (minus)
b) CH3OH
HCl is a very polar substance like water, and therefore prone to dissolution in water.
CH3OH has a lipophile and a hydrophile component. However the lipophile component (CH3) is very short an spherical, and the OH - component is prone to the protones in watermolecules.
CH3OH would also partially dissoziate into H3O (plus) and CH3O (minus) iones.
CS2, C and C2H6 won't dissolve in water, they won't even mix.
