Concept explainers
(a)
Interpretation:
The product for the given nucleophilic elimination step with appropriate curved arrows is to be drawn.
Concept introduction:
In nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This is the electron rich atom, and the less electronegative atom bonded to the electronegative atom is relatively electron poor. The curved arrow drawn from the lone pair of electron rich atom points to bonding region between the more electronegative atom and less electronegative atom, representing the electron flow from the electron rich site to the electron poor site. The second curved arrow is drawn to represent the breaking of bond between the less electronegative atom and leaving group to avoid exceeding an octet on the less electronegative atom.
