1. The problem statement, all variables and given/known data 8) How might you prepare each of the following molecules using a nucleophilic substitution at some step? a) (CH3)3-O-CH3 b)CH3CH2CH2CH2CN 2. Relevant equations none 3. The attempt at a solution I'm really not sure what's being asked. I'm going to assume that I need to pick a leaving group and substitute it with some kind of nucleophile... So...for part a I chose O for the leaving group and part b I chose CN as the leaving group. However, I have no clue where to go from there...what am I trying to create? Thanks for any help!!
