Question
Chapter 26, Problem 44PP
Interpretation Introduction
Interpretation:
Mechanism for transesterification of trimyristin using isopropanol in presence of acid catalyst need to be drawn.
Concept introduction:
Transesterification is a process in which the alcohol group present in the carboxylate of triglyceride is exchanged by another organic alcohol group. The general scheme can be shown as,
The steps involved in transesterification is,
- Protonation
- Nucleophilic attack
- Deprotonation
- Protonation
- Loss of leaving group
- Deprotonation
To draw: the mechanism of transesterification of trimyristin using isopropanol in presence of acid catalyst.

2) (4 pt) After the reaction was completed, the student collected the following data. Crude
product data is the data collected after the reaction is finished, but before the product
is purified. "Pure" product data is the data collected after attempted purification using
recrystallization.
