This is a bimolecular reaction. It happens in a single smooth step.

Halogen atoms (fluorine, chlorine, bromine, and iodine) are more electronegative than carbon. This difference in electronegativity pulls the electron density in the -bond toward the halogen atom.
Chemsheets often includes a task linking bond enthalpy to reaction rates. R−X+2NH3→R−NH2+NH4+X−cap R minus cap X plus 2 cap
