Questions and Answers

What is a characteristic of aromatic rings that enables them to participate in van der Waals interactions with the active site?

  • Their capacity to form covalent bonds with the active site
  • Their planar and hydrophobic structure (correct)
  • Their ability to form hydrogen bonds with the active site
  • Their ability to form induced dipoles with the active site

    • Why does the cyclohexyl ring not bind well to the active site?

  • Due to the presence of axial protons that can interact strongly with the active site
  • Due to the planar shape of the cyclohexyl ring
  • Due to the ability of the cyclohexyl ring to form hydrogen bonds with the active site
  • Due to the steric bulk of the cyclohexyl ring that prevents it from fitting into the narrow binding slot (correct)

    • What is the characteristic of alkenes that makes them easier to reduce than aromatic rings?

  • Their ability to form hydrogen bonds with the active site
  • Their higher energy state compared to aromatic rings (correct)
  • Their planar and hydrophobic structure
  • Their ability to form induced dipoles with the active site
