Chloroform soluble?

When we check the solutiblity in water, do we have to check H-bonding? Or Do we only have to check polar or non-polar?
Then, popanol is soluble due to the H-bonding or due to the electronegative O?
Chloroform is insoluble, but Cl is electronegative and would be slightly polar, which makes it soluble?

Little bit of both. H-bonding increases solubility. Of course, the O-H bond itself is highly polar and will render the molecule some polarity.

Chloroform is insoluble in polar solvents, because it has a small dipole moment. Furthermore, when it comes to solvents you must take into account factors like the dielectric constant. Chloroform has an extremely small dielectric constant, which makes it essentially non-polar, explaining why it's not soluble in polar solvents.


Generally speaking, like dissolves like (Polar compounds are soluble in polar solvents while non-polar compounds are soluble in non-polar solvents). So, determining polarity is important!
H-bonding will increase the extent, to which a substance is soluble.
