Our Gold Standard DAT Organic Chemistry Reactions and Summary page is not intended to be an exhaustive ORG review. That requires much more than one page. However, we hope you find a helpful summary of key organic chemistry reactions to help make your DAT review a bit easier. Consider printing the reactions and reviewing the logic frequently. As much as possible, try to make sense of the reactions and avoid memorizing. You will notice reactions that are numbered and then described below. If you happen to have the Gold Standard DAT Chemistry book, we have placed the cross-reference to the section of the book for more information regarding any reaction or mechanism (i.e. ORG 4.2 = Organic Chemistry chapter 4, section 4.2).

R = alkyl

Et = ethyl

X = halide

R-MgX+ = grignard reagent

R-Li+ = alkyl lithium

Grignard reagents and alkyl lithiums are special agents since they can create new C—C bonds.

*Reduction = addition of hydrogen or subtraction of oxygen. Mild reducing agents add fewer hydrogens/subtract fewer oxygens. Strong reducing agents add more hydrogens/subtract more oxygens. Cross-referencing to The Gold Standard DAT text.

Most reactions presented can be derived from basic principles (i.e. ORG 1.6, 7.1).

Can't I use MCAT books instead?

There are many important DAT General and Organic Chemistry topics that are either not on the MCAT or are so rare as MCAT questions that the topics are not properly covered in MCAT books. Here is a partial list: general chemistry laboratory techniques and glassware, alkene, alkyne, ether and aromatic chemistry, multi-step organic syntheses, etc. The Gold Standard DAT was designed specifically for the DAT so all ADA topics are presented in color followed by chapter review questions, answers and explanations.

Table of Contents for Organic Chemistry

  1. Molecular Structure of Organic Compounds
  2. Stereochemistry
  3. Alkanes
  4. Alkenes
  5. Aromatics
  6. Alcohols
  7. Aldehydes and Ketones
  8. Carboxylic Acids
  1. Carboxylic Acids Derivatives
  2. Ethers and Phenols
  3. Amines
  4. Biological Molecules
  5. Separations and Purifications
  6. Spectroscopy

Key Organic Chemistry Reaction Mechanisms

Official ADA DAT Organic Chemistry Test Content (30 questions)

  1. Mechanisms:

    Energetics, and Structure - elimination, addition, free radical, substitution mechanisms, and other mechanisms and reactions.

  2. Chemical and Physical Properties of Molecules:

    Spectroscopy (1H NMR, 13C NMR, infrared, and multi-spectra), structure (polarity, intermolecular forces (solubility, melting/ boiling point, etc.), and laboratory theory and techniques (TLC, separations, etc.)

  3. Stereochemistry (structure evaluation):

    Chirality, isomer relationships, and conformations

  4. Nomenclature:

    IUPAC rules and functional groups in molecules

  5. Individual Reactions of the Major Functional Groups and Combinations of Reactions to Synthesize Compounds:

    Fertilization, descriptive embryology, developmental mechanisms.

  1. Genetics:

    Alkene/alkyne, aromatic, substitution/elimination, aldehyde/ketone, carboxylic acids and derivatives, and other. For each area listed above, the following sub-areas apply: general, one-step, and multi-step.

  2. Acid-Base Chemistry:

    Ranking acidity/ basicity (structure analysis and pH/ pKa data analysis), and prediction of products and equilibria

  3. Aromatics and Bonding:

    Concept of aromaticity, resonance, atomic/ molecular orbitals, hybridization, and bond angles/lengths.
