4. Propose a synthesis to create 3,4-dimethyl-3-hexanol from 1-butene. You only need to show individual steps and reagents, you do not need to show mechanisms. You must use 1-butene as your ONLY source of carbon atoms. The convergent processes have been outlined for you. for STEP 1: Show how to synthesize butyl magnesium bromide from 1-butene (5 points): BrMg STEP 2: Show how to synthesize 2-butanone from 1-butene (5 points): STEP 3: What intermediate forms below and what reagent(s) will...
please show work. will rate.
