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.

Hello everyone! I am sorry in advance for so many questions. There is experimental procedure for benzocaine synthesis from p-aminobenzoic acid: 12 ml of ethanol and 0.9 g of p-aminobenzoic acid was added and stirred until dissolving after 1 ml of conc. H2SO4 was added. Then it was heated under reflux for 40 minutes and cooled, next the mixture was transferred into 250 ml flask with 30 g of ice and 30 ml of water and 10 ml of 10%...
