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...

Is SN2 concerted or stepwise correct answer: Concerted Is SN1 concerted or stepwise correct answer: Stepwise When is there a change in configuration in an SN2 correct answer: When alpha position is a chiral center What type of substrate reacts most quickly for SN2 correct answer: Primary What type of substrate reacts most quickly for SN1 correct answer: Tertiary (bc more stable carbocation) What type of nucleophiles favor SN2 correct answer: Strong List 9 strong nucleophi...

Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Correct List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to initiate the reaction. The reaction flask is covered and stirred to conduct reaction to prevent evaporation...
