Step-by-step explanation:
Water is only able to dissolve polar molecules and ions. This is because, for a substance to dissolves in water, it has to positively interact with the water molecules (that have partial positive and negative charges). H-bond will form between the partially positive hydrogen ends of water molecules and the negatively-charged ends of the dissolved molecules. The partially negative oxygen ends of the water molecules, on the other hand, interact with the positively-charged ends of the dissolved molecules.
Molecules with no charge are hydrophobic.
