I know the answer is E, but I am confused why III is accurate. If attraction increase proportionally to distance, wouldnt the distance being raised to the -6 power make the attraction decrease as distance increased? Can someone explain this for me? 25. Which of the following statements is true of Van der Waals' interactions? I. They are a type of non-covalent interaction II They contribute to protein stability in hydrophobic molecules. 111. The attractive force (V) of Van der...
1. Which of the following amino acids has the most hydrophobic side chain? a). E b). F c). S d). W e). Y 2. Which type of non covalent interaction would you expect to be present between Cl- and H2O? a). Ionic interactions ("salt links") b). Hydrogen bonds c). Van der Waals interactions d). Ion-dipole interactions For the first question, I have F and W both being hydrophobic chains but am unsure why or how to tell which one would...
