PRINTER VERSION BACK NEXT x Your answer is incorrect. Try again (b) Consider the opposite problem, that of carrying out a substitution reaction on a tertiary alkyl halide. Use as your example the conversion of tert-butyl chloride to tert- butyl ethyl ether. What experimental conditions would you employ to ensure the highest possible yield of the ether? Select all that apply. Polar protic solvent High temperature Absence of strong base (solvent is often the base) Strong unhindered base,e.g., CH3CH2ONa (EtONa),...

For O. Chem lab titled: "Perfumes: The Synthesis of Nerolin".
Please answer questions 16 (a-c) and 17.
Nerolin chemically is called either 2-ethoxynaphthalene or ethy! S-naphthy! ether and can be prepared by the following Williamson synthesis of ethers. OH O-CH.CH - 1-CH.CH KOH alcohol +H.O+KI Waphthal Ethyl iodide Nerolin The potassium hydroxide, acting as a base, removes the slightly acidic proton from 6-naphthol and converts it into the nucleophile potassium B-naphthoxide, which attacks ethyl iodide and displaces the iodide ion....

Q: Calculate the expected mass of both methyl salicylate and

EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...

What is the theoretical yield (in grams) and percent yield of your
triphenylmethanol product in this experiment? (Weight of
triphenylmethanol: 0.060g)
BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...
