What are the correct answers?

Which of the following statements is false? Van der Waals interactions are too weak to be a significant attractive force. lonic interactions are stronger in non-polar environments than in polar environments. Hydrogen bonding strength depends on the orientation of the atoms involved. Hydrogen bonds are weaker than covalent bonds Ionic interactions do not depend on the relative orientation of the ions. Question 8 (Mandatory) (1 point) Hydrogen bonds are strongest when: they occur on the protein surface, due to their interaction with water molecules. the hydrogen is in a straight line between two electronegative atoms and shielded from water. they are involved in pairing of G and C bases in the DNA double helix. the dielectric constant (D) is at the maximum value of 80. Hydrogen bonds are not really bonds, but reflect the increased entropy of the solvent water
