Answer for Question number 1:
Griganard reagent is extremenly reactive with water and it can undergo hydrolysis, which gives you alkane. If your round bottom flask is having moisture or water, it will react with your Grignard reagents.
Answer for Question number 2:
Grignard reagents are RMgX, where magnesium cordinate or chelate with ether oxygen atoms and forms a complex which solidify during the reaction.

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...

Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...

BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...

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...
