Question
Chapter 23, Problem 23.78P
Interpretation Introduction
(a)
Interpretation: The stepwise mechanism to explain the given result is to be drawn.
Concept introduction: Carbonyl compounds in presence of base, loses its alpha hydrogen to form enolate. Enolates have negatively charged oxygen with adjacent carbon-carbon double bond. Enolates are resonance stabilized species.
Interpretation Introduction
(b)
Interpretation: The validation of the fact that optically pure isomer is obtained regardless of the amount of base used in litorene is to be stated with an explanation.
