Q21-8P

Question


If the following molecule is treated with acid catalyst, an intramolecular esterification reaction occurs. What is the structure of the product? (Intramolecular means within the same molecule.)




Step-by-Step Solution

Verified
Answer


The product structure can be drawn as,




1Step 1: Steps involved in the reaction mechanism

The steps can be followed as,

  1. Carboxyl oxygen protonation
  2. The C=O bond opening will leads carboxyl carbon to nucleophilic attack from oxygen nucleophile bond molecule.
  3. The protonation of H+ of carboxylic will convert into leaving group.
  4. The water elimination by C=O restoration will regenerates the catalysts and ester formation
2Step 2: Drawing the structure of the product


The product structure can be drawn as,
