One of the conceptually simpler molecular changes into which an
elementary reaction
can be notionally dissected. Such changes include bond rupture, bond formation, internal
rotation, change of
bond length or bond
angle, bond
migration, redistribution of charge, etc. The concept of primitive changes is helpful in the
detailed verbal description of elementary reactions, but a primitive change does not
represent a process that is by itself necessarily observable as a component of an
elementary reaction.
