Point fixed to the location of one or more atoms.
Molecule graph object.
Electron flow arrow.
Representing the movement of one or two electrons in a reaction as a curved arrow.
Electron flow can start from any atom or bond, but not from any atom pairs that has no connection bond.
The logic of the electron flows: If the source is an Atom, the sink can be: any Atom Bond connected to this Atom an atom pair from this atom and any other atom (incipient bond) If the source is a Bond, the sink can be: one of the Atoms on the end of this Bond a Bond connected to this Bond (has common ending Atom) an atom pair from one of the Atoms on the end of this Bond and any other atom (incipient bond) If only the sink/source is in an sgroup, the sink/source must be the attachment point.
Electron flow arrow base point.
