TRUE OR FALSE
1. In a nonpolar bond, the electronegativity difference of the bonded atoms
should be 0.4 or less
_______________ 2. In a polar bond, electrons are shared between atoms.
_______________ 3. A nonpolar molecule has a dipole
_______________ 4. In a polar bond, the electronegativity difference of the atoms must be
greater than 1.9
_______________ 5. Nonpolar molecules have positive or negative ends.
_______________ 6. Boiling point, melting point, solubility and electro negativities are some
of the properties of the molecules that may affect the polarity of the
molecules.
_______________ 7. The term “Like Dissolves Like” explains that polar solvent dissolve polar
solute, while nonpolar dissolve nonpolar.
_______________ 8. Polar molecules are symmetric, because having atoms with different
electro negativities bonded.
_______________ 9. A water molecule, H2O, is a nonpolar molecule because of unequally
shared electrons with the oxygen atom spending more time with
electrons than the hydrogen atoms.
_______________ 10. Molecular polarity controls or determines the strength and types of
intermolecular forces of attraction between molecules
