Unformatted text preview: bond of 2 non-metal atoms, with the same electronegativity, resulting in an equal sharing of the bonded electron pair. So the electronegativity of 2 non-metal atoms determines whether the bond is either polar or non-polar. 4. Hydrophilic substances like water and are normally charged or polar compounds. Whereas hydrophobic substances don’t like water and are normally non-polar. Substances are hydrophilic when a molecule is likely to form a bond with the Hydrogen molecule in water. Substances are hydrophobic when a molecule repels water and aren’t soluble in water. 5. Ethanol is more hydrophilic because the hydroxyl group on the ethanol can form bonds with water molecules. Also, ethanol is polar while ethane is non-polar; therefore, ethanol is going to be more hydrophilic....
