Anhydrous conditions are vital for a successful Grignard synthesis. To demonstrate this point calculate the mass of the water it would take to destroy the phenylmagnesium bromide you will synthesize. What is he volume of this amount of water?
-How exactly do you do this?

  1. What compound are you trying to make?
    I would write an equation, something like this:
    RMgX + HOH ==> RH + MgXOH
    I'm assuming you aren't trying t make the RH compound but this is one method for preparing alkanes or ArH
    Then use freshman stoichiometry to calculate the mass of water from the reaction that will react with the amount of the phenylMg Br.

    If, by mistake, a chemist used 100% ethanol rather than diethyl ether as the reaction solvent, would the Grignard synthesis still proceed as expected?
