SYNTHESIS OF T-PENTYL CHLORIDE LAB
Provide a stoichiometry table for the reaction being performed
in this lab.
PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...

QUESTION: Show the mechanism of the reduction of 3-dimethylaminopropiophenone hydrochloride to form the alcohol? PROCEDURE: Add 2.00 g of 3-dimethylaminopropiophenone hydrochloride, 10 mL of distilled water and a magnetic stir bar to a 100 mL beaker, and stir to dissolve. This is the reaction beaker. Add (with stirring) sufficient 10% NaOH (about 5–6 mL) to bring the solution to pH >10. The free base will form and come out of solution as a milky oil. With continued stirring, add enough...

MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...

I need help with my pre and post lab questions.
The three compounds below were spotted on a TLC plate and developed to give the TLC plate shown. Which compound corresponds to which spot? Calculate the Rf value for spot B in the TLC plate shown above. When using polarity to determine the relative rates at which organic compounds travel up the TLC plate, we are considering compounds of similar molecular weight. It should also be noted that Rf values...

Thumbs up for good answer. Why does the liquid in the round
bottom flask turn light pink?, please explain (This happened
during/after step 2). This is the procedure and the experiment is
called Synthesis of Artificial Flavorings by Fischer
Esterification.
Thank you!
