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...

This procedure was conducted for diethyl n-butylmalonate. The
question is: What is the purpose of the tricaprylmethylammonium
chloride and why is it used in a nomstoichiometric?
Chapter 42 Malonic Ester of a Barbiturate 541 Into a 5-mL long-necked, round-bottomed flask, weigh 40 mg of tricaprylmethylammonium chloride, 400 mg of diethyl malonate, 350 mg of 1-bromobutane, and 415 mg of anhydrous potassium carbonate. Attach the empty distillation column as an air condenser and reflux the mixture for 1.5 hours (Fig. 42.1)....

Determine the yield limiting reagent and the theoretical yield for the following multistep synthesis from the reaction of ethyl acetoacetate. Draw the chemical complete chemical reaction and mechanism of Product C (determined to be 4-hydroxy-4 4-diphenylbutan-2-one) to Product E provided the procedure below. Procedure Step 4B [Product C to Product E] Place product [C] (0.5 g) in a 50 mL round bottomed flask, add acetone (15 mL), and concentrated HCl (2.5 mL). Boil under reflux on a water bath for...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
