MS 907 - Alkene Addition and Elimination Mechanisms Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 6

Keywords: alkene addition, carbocation, dehydration, E1 mechanism

Description: This mendel set is a complement to Carbocation Drills. It is meant to prepare students on how to approach longer and more complicated mechanisms. Reaction mechanisms covered:

  • Acid-catalyzed elimination (dehydration, E1)
  • Acid-catalyzed addition to an alkene
  • Halohydrin formation (halonium ions, which result in anti-additions.)

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 7

Keywords: chiral resolution, Fischer projections, R and S configuration, stereochemistry

Description: This mendel set covers various stereochemistry topics, such as:

  • Assigning R/S configuration
  • Fischer projections
  • Identifying meso molecules
  • Stereoselective reactions (are the products racemic or optically active?)
  • Chiral resolutions

MS 904 - Carbocation Drills Submitted by Matt on August 6, 2011.

Textbook and Chapters: Carey and Giuliano 8th Ed. (2010), Chapters 4, 5, 6

Keywords: carbocation, carbocation formation, carbocation rearrangement

Description: This mendel set guides you through everything you have to know about carbocations:

  • Ways carbocations form
  • Carbocation rearrangements
  • How carbocations react (elimination or nucleophilic attack)

Also includes some practice problems: addition to an alkene, dehydration (E1), and substitution (SN1).

MS 902 - Formal Charge and Resonance Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 1

Keywords: formal charge, Lewis structures, resonance

Description: This mendel set goes through the basics of structure:

  • Converting between formulas and carbon skeleton diagrams ("Zig-zag" structures)
  • Determining formal charge
  • Identifying implicit hydrogens and lone pairs
  • Resonance and arrow pushing

MS 901 - Acid-Base Practice Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 1

Keyword: acid strength

Description: This mendel set goes through rules that affect acid and base strength:

  • Negative charges are best on more electronegative atoms (left to right on periodic table).
  • Negative charges are best on larger atoms (up to down on periodic table).
  • Resonance stabilizes charges. The more resonance forms the better.
  • Neutral compounds are in general more stable than changed ones.

"What makes a compound stable?" problems are key to understand for the MCAT.
