these intermolecular forces are found in polar molecules * 1 point
hydrogen bonds
dipole - dipole forces
london dispersion forces
out of the intermolecular forces, which ones are the strongest forces of attraction? * 1 point
hydrogen bonds
dipole - dipole bonds
london dispersion forces

Explanation:

1. Polar molecules have a separation of positive and negative charges. Dipole - dipole forces occur between the positive end of one polar molecule and the negative end of another. Hydrogen bonds are a special type of dipole - dipole force but require hydrogen bonded to a highly electronegative atom. London dispersion forces are present in all molecules (polar and non - polar) due to temporary dipoles. So, the intermolecular forces found in polar molecules are dipole - dipole forces.
2. Among intermolecular forces, hydrogen bonds are the strongest. They are a special type of dipole - dipole interaction that occurs when hydrogen is bonded to a highly electronegative atom (N, O, F). Dipole - dipole forces are weaker than hydrogen bonds and London dispersion forces are the weakest.

Answer:

1. B. Dipole - dipole forces
2. A. Hydrogen bonds
