3. Find and label the major product for the following reaction: EtOH Br

Answer 1

The reaction will procede via Sn2 reaction mechanism. This will result in the inversion of stereochemistry of product because the incoming nucleophile attacks from the backside.

The major product and complete mechanism is shown below:

CH3 CH3 OH oh OH Br (2R-Bromo-1R-methyl-propyl)- cyclohexane Transition state CH3 OH 3-Cyclohexyl-butan-2R-01 Majot product
