At reflux: At room temperature: TEMP Group B Substitution or Elimination As you have learned in lecture, substitution reactions and elimination reactions are competing reactions and the outcome of any reaction depends on several factors, most importantly tem- peratune, and the structure of the alkyl halide. This group will examine competition between substitution ánd elimimation reaction. Br NaOCH3 + (3-bromopropyl)benzene In a 25 mL round-bottom flask, add 2 mL of...

What is the reaction product(s) of oleic acid & sodium methoxide? Show the structure(s). Part A: Acid Catalyzed Fischer Esterification of Free Fatty Acids Add 20 mL of canola oil and a magnetic stir bar to a 125-mL Erlenmeyer flask, and place the flask on a magnetic stirring plate. Add 2–3 mL of methanol and up to three drops of concentrated sulfuric acid Perform this step with caution, as this is a strong acid! Immerse a thermometer into the reaction...
Organic chemistry post-lab question: "Why is important to add the alkyl halide dropwise in your reaction?...
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...

A Grignard reaction was performed using the following steps: Step 1: Addition of Grignard Reagent: Phenyl Magnesium Bromide a solution of phenyl magnesium bromide (2.7 mL of a 3.0 M solution in anhydrous diethyl ether) and 5 mL of anhydrous diethyl ether was dispensed into the round-bottom flask and stirred with a stir bar. Step 2: Addition Formation: Reaction with Benzophenone A solution of 0.72 g (mp = 48-49 degrees C) of benzophenone and 2.0 mL of anhydrous diethyl ether...

1. What was the sodium sulfite used for the experiment below? 2. What material could still be in the ether layer of the experiment below? To a 3.0 mL conical vial containing a spin vane and equipped with an air condenser, add 20 uL of acetophenone and 700 uL of household bleach ( NaOCl, 5% available). Dispense both reagents in the hood! Stir the mixture at room temperature for thirty minutes. Add approximately 5.0 mg of sodium sulfite and stir...
