Why does a structure like H – C = C – H fail to make sense chemically?

  • Differentiate between hydrogen bonding and van der Waals bonding.
  • If you were a pharmaceutical researcher, why would you want to learn the three-dimensional shapes of naturally occurring ligand (signal) molecules?
  • What does it mean that the electrons of an atom are excited?
  • Differentiate between dehydration synthesis and hydrolysis.
slide2

List the three types of isomers we learned and give an example of each.

  • Differentiate between polymers and monomers.
  • Define functional groups.
  • Describe how the properties of water contribute to the upward movement of water in a tree (more than two properties apply).
  • How can freezing of water crack boulders?
  • Explain how carbonic acid can act as a buffer.
slide3

Explain how the polarity of water molecule allows it to form hydrogen bonds.

  • Explain the following graph by relating it to the physical and chemical properties of water:
slide4

When a dog pants, holding its mouth open, what property of water allows loss of heat and subsequent reduction of the dog’s internal temperature?

  • Describe what happens with water when it dissociates.
  • Compared with a basic solution at pH 9, the same volume of an acidic solution at pH 4 has ____ times as many hydrogen ions.
  • Differentiate between the dissociation of strong acids and weak acids. Chose which one would be a good buffer and explain why.
