Interpretation:
Curved arrows are to be added to the polar reaction given to indicate the flow of electrons.
Concept introduction:
Curved arrows are drawn such that they start from a nucleophilic source (neutral or negatively charged) and end in an electrophilic sink (neutral or positively charged). During the flow of the electrons the octet rule must be maintained. The formation of a new bond will be accompanied by the breaking of an existing bond.
To add:
Curved arrows to the polar reaction given for indicating the flow of electrons.
b)
Interpretation:
Curved arrows are to be added to the polar reaction given to indicate the flow of electrons.
Concept introduction:
Curved arrows start from a nucleophilic source (neutral or negatively charged) and end in an electrophilic sink (neutral or positively charged). During the flow of the electrons the octet rule must be maintained both in the source and sink.
To add:
Curved arrows, to the polar reaction given, to indicate the flow of electrons.
