Chapter 16, Problem 64P
- a. When a
carboxylic acid is dissolved in isotopically labeled water (H2 18O) and an acid catalyst is added, the label is incorporated into both oxygens of the acid. Propose a mechanism to account for this.
- b. If a carboxylic acid is dissolved in isotopically labeled methanol (CH3 18OH) and an acid catalyst is added, where will the label reside in the product?
- c. If an ester is dissolved in isotopically labeled water (H2 18O) and an acid catalyst is added, where will the label reside in the product?
