    I don't get why is[​IMG] more soluble in pentane than [​IMG] I understand that its because ether is nonpolar, but 1,4 Diaminobenzene looks non-polar to me also, since it's symmetrical? I'm missing something here...

    im not positive so dont hold me to it...but maybe its because since pentane is not a suuuuper long hydrocarbon (kinda short) it resembles water more than it does a long hydrocarbon like decane, etc.

    Since its more like water...its gonna make Hydrogen bonds with that first molecule....rather than non-polar bonds to the diamino molecule ...
