We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...

What is the major product of the following reaction?
Please explain why there is not
a retention of configuration for the ethyl. I get that this is an
E1 elimination. That the NaoMe has to take from the beta carbon
attached to the ethyl because that is the anto-periplanar hydrogen.
What I dont understand is why the ethyl group changes and why
answer C is not the answer. Thank you!

Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
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...

Assuming that all other experimental conditions are the same; explain if an SN1 reaction would still occur if the following changes were made. If an SN1 reaction would still occur: then state the IUPAC name and draw the structure of the product formed compare the rate of reaction to the rate of the original reaction (in this experiment), meaning would the reaction occur more slowly, or more rapidly? If an SN1 does not occur: state the type of reaction that...
