We’re being asked to determine the solubility of benzene in water (H2O). Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.
Water exhibits hydrogen bonding, so the best solute is another polar compound that also exhibits hydrogen bonding. So for this, we will look at the Lewis structures of benzene and determine their polarity.
Is glucose soluble in water?
