MS 917 - Alcohol and Carbonyl Redox Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 15

Keywords: alcohols, hydride reduction, oxidation

Description: Goes over how alcohols can be oxidized to form aldehydes/ketones and carboxylic acids, which can be transformed further using Grignard reagents, hydride reagents such as NaBH4, and by performing Fischer esterification. Includes several synthesis problems involving carbonyls and epoxides. Also includes an NMR based problem.

Total Problems: 5

MS 914 - Mass Spec Practice Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 13

Keywords: alpha cleavage, heterolytic cleavage, homolytic cleavage, mass spec

Description: Goes over alpha-cleavage and the McLafferty rearrangement in mass spectrometry.

MS 913 - Benzene EAS Reactions, EDG/EWG, and ortho/meta/para Directors Submitted by Matt on August 6, 2011.

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 12

Keywords: EAS mechanism, EDG and EWG, Friedel-Crafts

Description: Covers electrophilic aromatic substitution (EAS) reactions in detail.

It includes many, many resonance exercises that show why:

  • Electron donating groups (EDG) are ortho-para directors
  • Electron withdrawing groups (EWG) are meta-directors
  • Pyrrole undergoes EAS at C-2 and not C-3
  • Pyridine undergoes EAS at C-3 and not C-2 or C-4
  • Naphthalene undergoes EAS at C-1 and not C-2

Total Problems: 11

Textbook and Chapter: Carey and Giuliano 8th Ed. (2010), Chapter 11

Keywords: aromaticity, benzylic position, heteroaromatic compounds

Description: Goes over benzene, aromaticity, and the benzyl position (1 carbon away from benzene).
Lots of aromatic resonance practice.

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

Keywords: leaving groups, nucleophilicity, SN1/SN2/E1/E2

Description: Goes through substitution and elimination competition reactions:

  • Nucleophile strength trends
  • Leaving group trends

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.)
