please help! thank you 47) Draw out the reaction mechanism for a Fischer esterification reaction with...
Hello! Could you please draw the generic mechanism for Fischer esterification for the synthesis of benzocaine from p-aminobenzoic acid and ethanol catalysed by conc. H2SO4 and if it is possible explain steps Thank you so much!
Fischer esterification lab question, Please help. Thank you in advance 1) In the synthesis of isopentyl ethanoate, whose reaction is shown below a) what is the purpose of the sodium bicarbonate solution in the isolation step? b) what is the purpose of adding molecular sieves to the reaction? c) what is the purpose adding sulfuric acid to the reaction? d) why is acidic acid added in excess? e) what is the purpose of conducting a semi-micro distillation in the second...
Using the mechanism shown in Figure 1 as a template, draw out the mechanism for the Fischer Esterification reaction that occurs between butyric acid and isobutanol. Figure 1.

In the Fischer esterification reaction, a carboxylic acid reacts with an excess of alcohol in acidic conditions to form an ester. During the reaction the sp2 hybridized carbonyl carbon of the acid forms an sp3 hybridized intermediate before returning to sp2 hybridization in the product. Draw the structure of the neutral sp3 hybridized intermediate and the ester product in the reaction between pentanoic acid and n-propanol.

Draw a mechanism for an esterification reaction between phthalic anhydride and ethylene glycol under acidic conditions. (I need help seeing how this reaction would occur with a molecule such as phthalic anhydride, thanks!)
Q7. Below is a reaction mechanism for the Fischer Esterification process. Identify the indicated steps (1 - 4), and what is general term for the intermediate A commonly known as? H -- CH CH CH پوت : كل ال OH2 :0: Step Name 1 2 3 A 2.5 marks Q8. Generally, esters have lower boiling points than their parent carboxylic acid do. Why might this be the case? 0.5 marks Q9. Name one reagent/method that can be used for removing...
In the boxes provided, draw the structures of the four intermediates and the organic product when the following compound is reacted with methanol in the presence of acid in a Fischer esterification reaction. You don’t have to show the important resonancestructures.I need to see the mechanism to get the answers.
Could you please help and draw this mechanism? Thank you! 3. Ille meeldiSM UI we ledCLIUI. 4. In place of the written protocol show the mechanism of the following reaction and determine how many products can form. Indicate the full mechanism for ONE product formation but show all potential final products that can occur. Reactions must be hand-drawn! KH ethanol
Please answer Q2. Will upvote, guaranteed. Thank you and much appreciation. A) Draw the complete mechanism for the following esterification reaction. Please use curved arrows to indicate electron flow. B) Provide the IUPAC name for the final product. 2. OH (311 11
