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
.
