DAT Organic Chemistry Study Review Practice Test. Enantiomer - CORRECT ANSWER Non-superposable mirror images Diastereomer - CORRECT ANSWER Non-mirror images with same chemical formula Meso Compound - CORRECT ANSWER Achiral but has stereocenters Why are axial conformations of large substituents less stable than equatorial conformations? - CORRECT ANSWER 1, 3 diaxial interactions What rings have more ring strain? - CORRECT ANSWER Smaller rings, but not cyclohexane General formu...

SN1 Reaction - ANSWER- Unimolecular nucleophilic substitution - 2 steps - Starting with enantiomerically pure product tends to result in some degree of racemization - Retention AND inversion at stereocenter (R and S) - 1 nucleophile is replaced by another nucleophile - Carbocation INTERMEDIATE forms - Rate is dependent only on substrate concentration 1. LG leaves, forming a carbocation 2. Nucleophile attacks the carbocation, forming the product SN2 Reaction - ANSWER- Bimolecular nuc...
