QUESTION 41 The reaction of an alcohol with a carboxylic acid under acidic conditions results in...
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.
Which reactant provides the oxygen atom found in the ester
linkage: Pentanoic acid, or...
