The weight of triphenylmethanol is 0.060g
QUESTIONS 1. (4 Points) What is the theoretical yield (in grams) and percent yield of your triphenyl- methanol product in this experiment? EXPERIMENTAL PROCEDURE All glassware used in a Grignard reaction must be scrupulously dried. Dry the following glassware in an oven at 110°C for at least 20 minutes: drying tube, Claisen adapter, 8 mL conical vial, 5 mL conical vial, air condenser, glass stirring rod, and a magnetic spinvane. DO NOT PLACE O-RINGS...

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...
