Answer:

  1. Water (H2O) - Polar. Water has polar covalent bonds due to the difference in electronegativity between hydrogen and oxygen.
  2. Carbon dioxide (CO2) - Nonpolar. The carbon-oxygen bonds are polar, but the overall molecular structure is symmetric, resulting in no net dipole moment.
  3. Methane (CH4) - Nonpolar. The carbon-hydrogen bonds are nonpolar due to the similar electronegativity of carbon and hydrogen.
  4. Ethanol (CH3CH2OH) - Polar. The molecule has a polar O-H bond, making it polar overall.
  5. Sodium chloride (NaCl) - Ionic. The large electronegativity difference between sodium and chlorine results in an ionic bond.
  6. Oxygen (O2) - Nonpolar. The oxygen-oxygen bond is nonpolar.
  7. Ammonia (NH3) - Polar. The nitrogen-hydrogen bonds are polar, giving the molecule an overall dipole moment.
  8. Carbon monoxide (CO) - Polar. The carbon-oxygen bond is polar.
  9. Hydrogen gas (H2) - Nonpolar. The hydrogen-hydrogen bond is nonpolar.
  10. Sucrose (C12H22O11) - Polar. The molecule contains many polar C-O and O-H bonds.
