Detailed explanation-1: -The following is not a property of water: A) nonpolar. Water is a polar molecule, due to its molecular structure. It is the polarity of water that gives it many of its unique properties. Water is polar because the oxygen atom in the molecule is more electronegative than the hydrogen atoms.
Detailed explanation-2: -Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. When put into polar environments, such as water, nonpolar molecules stick together and form a tight membrane, preventing water from surrounding the molecule.
Detailed explanation-3: -Water has the ability to dissolve many substances but the term “universal solvent” is misleading. Water is able to dissolve other polar molecules and ions, such as sugars and salts. However, nonpolar molecules like oils lack partial positive or partial negative charges, so they are not attracted to water molecules.
