I need help finding the theoretical yield (in grams) of triphenyl methanol product in this experiment. PLEASE SHOW WORK, I would like to learn the steps. below is pictures of the procedure with amounts of chemicals used 126 Experiment 10 EXPERIMENTAL PROCEDURE All glassware used in a Grignard reaction must be scrupulously dried, Dry the following glasstare in an af 110°C for at last 20 mini drying to Canadair 8 ml comical rial 5 ml con vial, air cond glass...
Find %yield please the product obtained was 0.0870g In the hood, place 100 mu L of aniline in a tared 10 times 75 mm (small) test tube. Place the test cube in a small beaker or Erlenmeyer flask to avoid spillage. Stopper the cube with a cork. Now, using a Pasteur pipet, add (with swirling) 0.5 mL of water, followed by three drops of concentrated HCI. Add 10 mg of decolorizing charcoal (we use the pelletized form, called Nonrit^TM) to...
NaBH4(Sodium Borohydride) Reduction of Ketone (Organic Chemistry Lab) Questions 1. Explain the reaction mechanism and why each reagent was used. 2. Explain the need for 2 different drying agents 3. Use IR stretches and melting point determination to explain your results. 4. Report sources of error. Experiment Procedure Assemble the reaction apparatus as shown in Figure 14.2a, consisting of a 3.0 mL conical vial charged with 4-t- butylcyclohexanone (amount calculated in pre-lab) and methanol (100 μL). Attach the air condenser...

any excess bromine that persists after the reaction will mostly be left in the choos: (filtered solid, filtrate, or reaction vile) and quenched with the choose: (oxidizing agent, reducing agent, strong acid, or strong base) choose: (acetic acid, methanol, sodium bisulfate, sodium bisulfite). Procedure: Bromination of E-Stilbene SAFETY INFORMATION Carry out this experiment in a fume hood and wear nitrile gloves. Pyridinium tribromide is an oxidizing agent, is corrosive, and can severe skin and eye burns. Glacial acetic severe skin...
