17.5 - Use the reaction of a Grignard reagent with Dimethyl ether of acyclic polyethers, Me(OCH2CH2)nOMe, predominantly coordinated to MgX2 in an ether solution of Grignard reagent and the MgX2 adduct was removed as a precipitate. How do you put grass into a personification? Before we proceed, here are the structures so we know what we're dealing with: We should see from all the benzene rings in all three compounds that the Grignard nucleophile is going to be an aryl anion. The mechanism  of the reaction involves the following three step:Step 1: Proptonation of ethene to form carbocation by electrophilic attack of H3O+.Step 2: Nucleophilic attack of water on carbocation.Step 3: Deprotonation to form an ethanol.
