Question
Chapter 8, Problem 8.48P
Interpretation Introduction
Interpretation: The reason as to why compound A does not undergo an E2 elimination with strong base is to be explained.
Concept introduction: E2 elimination reactions require the leaving proton and halogen atom to be present anti-periplanar to each other. Without meeting this condition, E2 reactions cannot proceed.
