Bonus Question (+5pts) Treating a nitrile (RCN) with a Grignard, following by aqueous acidic work-up gives in a ketone. While this might look like a new reaction, it is just a combination of two reactions you already know. Draw an arrow-pushing mechanism for this reaction. (Hint: The nitrile carbon is similar to another reactive carbon we have discussed already) 1) NH4ClMgCl2
