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...

1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...
