I need help with this post lab from Orgo. Anyone please help me. I have included...
Procedure Reaction: Add about 15 mL (measured precisely) of t-amyl alcohol to a 50 mL round bottom flask (the flask will become your stillpot). Cool the pot in an ice-water bath and slowly add, with swirling, about 5 mL of 9 M sulfuric acid. Add two boiling chips then clamp the flask to your ring stand. Do not leave the flask someplace it can be knocked over. Set up a fractional distillation with a foil wrapped Vigreux column. Use a...

You
don’t have to tell me purpose. just where in procedure for each
technique.
Section/Instructor SN2 Pre-lab (20 points) Answer on a separate piece of paper 1. (6 pts.) What is the purpose of the following experimental techniques and where in the procedure is each used? a. Heating under reflux b. Simple distillation c. Water wash d. Addition of COLD NAOH e. Saturated NaCl solution f. Addition of anhydrous sodium sulfate SN2 Reaction Procedure Set-Up: 100 mL RBF: 11.1 g...
I need help finding the theoretical yield (in grams) of
triphenyl methanol product in this experiment. PLEASE SHOW WORK, I

(If you need any more information just let me know) Determine the limiting reagent for the preparation of 2-bromo-2-methylbutane and calculate the theoretical yield of product. 1 CHEM-2223 Organic Chemistry Laboratory I Exp. 7: Synthesis of 2-chloro-2-methylbutane In this reaction a tertiary alcohol, 2-methyl-2-butanol, is converted to a tertiary halide, 2-chloro- 2-methylbutane through a SN1 reaction. 1) Chemicals 2-Methyl-2-butanol Hydrochloric acid, HCl (12 M) Saturated sodium bicarbonate Saturated sodium chloride (380 g/L) Anhydrous sodium sulfate...
Please can someone help me to interpret this. This was
from Orgo II Williamson ether Lab. These are the results and I need
help interpreting what this is showing. More especially for the
discussion and conclusion section. Thank You!
(if needed here are the procedures)
Add a magnetic stir bar to a 25ml round or pear-shaped
flask.
Add guaiacol (0.55ml,5mmoles) to the flask along with 3ml of
95% ethanol. Make sure the guaiacol dissolves in the ethanol before
proceeding.
Add...
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...
