Question
Chapter 25.3, Problem CQ
Interpretation Introduction
Interpretation:
The reaction included in the formation of steps 5 and 6 has to be given.
Concept Introduction:
The keto-group of carbonyl compound is in equilibrium with the enol form which contains alcohol group. The two groups are in equilibrium with each other and the enol form contains a double bonded carbon atoms adjacent to the alcohol group. The keto and enol compounds are said to be Tautomers and the mechanism is known as keto-enol tautomerization.
