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 pentanioc acid and n-propanol.

Please answer all questions and show all work 1. Write a mechanism for the acid-catalyzed esterification that uses cyclopentanol and acetic acid. 2. Tertiary alcohols do not work well in the procedure outlined for this experiment; they give a different product from what you might expect. Explain this and draw the expected product from t-butyl alcohol (2-methyl-2-propanol).

Pentanoic acid is primarily used for the synthesis of aromatic compounds of esters. A chemist wants to synthesize 2 Methyl Pentanoic acid in the laboratory. Discuss what could be the choice of the reactant that may lead to the synthesis of the desired product. Your answer must include four different steps (four different chemical reactions) leading to the synthesis of the desired product. All the organic compounds used/shown on the reaction must have a proper IUPAC name
