Choose which of the following statement regarding the interactions or bond is incorrect

#Unit 1. Structure and Function of Biomolecules
  1. in α- helices, the C=O and N-H groups of every interior residue participate in H bonds. -helices, the C=O and N-H groups of every interior residue participate in H bonds.
  2. Hydrophobic Interactions or hydrophobic clustering  entropically drive Protein Folding
  3. It is energetically favorable for an ionized residue to be located in the hydrophobic core of the protein.
  4. In Van der Waals Interactions the attractive forces are due primarily to instantaneous dipole-induced dipole interactions that arise because of fluctuations in the electron charge distributions of adjacent nonbonded atoms.
