Boiling Points of Alcohols. The oxygen in alcohols and phenols is sp 3 hybridized which gives the roughly the same tetrahedral geometry as water. The bond angle of methanol (108.5 o) is slightly less than the tetrahedral value mainly due to the presence of its lone pair electrons.. The presence of a highly electronegative oxygen confers a measure of polar character to alcohols.

Based on solubilities you can separate naphthalene and NaCl by adding the mixture to a volume of water. NaCl is highly soluble in water, so it will dissolve completely, while the insoluble naphthalen will remain solid. Next your filter the solution, washing the solid with pure water to eliminate all the NaCl from it.
