1. What two compounds X and Y, must be mixed in dry ether solvent to form C.HS-CH2- MgBr? CH2-MgBr X plus Y >> (identify X and Y) In questions 2-5 write the products of the following reactions, all performed in ether solvent. You do not need to show a water and HCl work-up step, but there is no penalty for doing so. You can simply leave your answer as a Lithium or Magnesium salt if you find that easier. 2. CH, MgB HO 3.
