Given the information below indicate whether the following combinations would be soluble or insoluble.?

Question

toluene C7H8 (l)-non polar methylamine, CH3NH2(l)-polar

a)toluene in water-

b)glucose in acetic acid

c) methylamine in toluene

d) acetic acid in octane

e) carbon tetrachloride in toluene

f) methanol in ethanol

How do you determine if they are soluble or insoluble

Answer 1

Well, toluene is not soluble in water.  It floats but will dissolve a bit when exposed to water.

I would think "f" is soluble because they are both alcohols.

How do I determine?  Chemistry -- but I was crummy in it so I can not tell you how I know other than I deal with toluene and water.
