What is the mechanism for the Barbier Reaction? Below are the reagents added to the reaction.

Add the following to the 50 mL round bottom flask:
     A) a mini magnetic stir bar
     B) 5 mL of aqueous saturated ammonium chloride solution
     C) 1 mL of THF
     D) 0.4 g of zinc powder (a curled up piece of weighing paper makes a good powder funnel)

Stopper the flask and ask your TA for the following....

     E) 0.509 mL of benzaldehyde (your TA will add this with an auto pipet)
     F) 0.433 mL of allyl bromide (your TA will also add this)

    Organic chemistry post-lab question: "Why is important to add the alkyl halide dropwise in your reaction? (Hint: your reaction is not heated, but you still need a water-cooled condenser!)" Please answer in detail! Here is a copy of the experiment, thank you! The Grignard reaction is an important synthetic process by which a carbon-carbon bond is formed. Magnesium metal is first reacted with an organic halide. The resultant organo-magnesium halide (Grignard reagent) is then combined with a carbonyl compound, ultimately...
