DAT Organic Chemistry: Key Reactions with Summary Review

DAT Reactions I • DAT Reactions II • DAT Reactions III • Substitution vs Elimination • Official Topics • GS ORG Review

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).

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.

In addition to the Dental Admission Test guides and software that we recommend to you, please consider visiting the official website for the Dental Admissions Test: click on DAT in the US or click here: DAT for students in Canada. Note: only the Canadian DAT includes manual dexterity/soap carving which is only covered in programs that specifically say so like the Canadian Edition of TopScore Pro.
