WebThere is a lot that goes into density, the size of the molecule is a large factor, but not the only one. Due to the H-bonds water makes with itself the molecules are tightly packed. Hexane (0,6g/cube cm) can't get 'packed' together as easily. The interaction of water with itself can also be seen by the next example: Methane (16g/mol) and water ... http://www.chem.ucla.edu/~bacher/Specialtopics/extraction.html

WebApr 7, 2024 · As the compound needs to be soluble in the boiling solvent, it helps if the compound and solvent have similar intermolecular forces. For example, if a compound can hydrogen bond (alcohols, carboxylic acids, and amines), it sometimes can be crystallized from water. If a compound has moderate polarity it sometimes is crystallized from ethanol. It is particularly important as a solvent in the production of cellulose plastics such as cellulose acetate.
