please answer all

1. What two compounds X and Y, must be mixed in dry ether solvent to form C6H5-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. CH2-MgBr . 3. CH -MgBr 4. LI . (R) 1111111 (R) Clearly show cis and trans, and R and S in your answer 5. H 1.X -- Li HHHH H Clearly show R and S or achiral in your
