Solublility

Hey,

Is there any method for determining solublility for O.Chem (meaning which functional groups are soluble in what solvent)...

Can anyone explain what we need to know regarding solubility for O.Chem?

Thanks

Compounds that can hydrogen bond will always dissolve in water.

Ions will also dissolve in water.

If the compound cannot hydrogen bond or be ionized, it will probably not dissolve in water.

Like dissolves like.

I meant in terms of functional groups and their solubility in acids, bases, and water...

Acids increase acidity in bases, bases increase acidity in acids.

compounds are readily soluble when the oxygen or nitrogen to carbon ration is 1:5 or lower. That is , one oxygen will cancel out up to 5 carbons. I'll check on this in my organic book when i get home but i think that is correct.

"an organic compound is water soluble only if it contains one polar functional group capable of hydrogen bonding with the solvent for every five C atoms it contains"

Can you please explain that statement. Thanks

what about ether being nonpolar?

i guess it cant donate and accept H bonds
