(iv) Inversion, retention and racemisation: There are three outcomes
for a reaction at an asymmetric carbon atom, when a bond directly
linked to an asymmetric carbon atom is broken Consider the
replacement of a group X by Y in the following reaction;
If (A) is the only compound obtained, the process is called retention
of configuration Note that configuration has been rotated in A If (B) is the only compound obtained, the process is called inversion
of configuration
