Question -

Let’s say you are instructed to collect your distillate (condensate) in four separate containers, 1 mL in each, during the fractional distillation of 4 mL of a (1:1) acetone-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the 1 mL fraction look different from that of the last 1 mL fraction? Can IR spectra help to identify if the fractional distillation is successful?

    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...
