i) Predict the product(s) for the major mechanistic pathwy(s). Show stereochemistry where applicable. If a racemate forms, draw one isomer and write racemate (This means that if there is an elimination, you only need to draw the major product of that. Or if there is a mixture of mechanism types, you would need the major product for each of the types) Write if the mechanism goes by SN2, SN1, E2 and/or E1. A. B. Br **** B NaCN CH₂OH
