IPA: /ˌhɛtəˈrɒlɪtɪk/
KK: /hɛtəˈrɑlɪtɪk/
Relating to a type of chemical reaction where a bond is broken and the electrons are unevenly distributed between the resulting fragments.
In heterolytic cleavage, one atom takes both electrons from the bond, leading to the formation of charged species.
Heterolytic → It is formed from "hetero-" (from Greek "heteros", meaning different) and "lytic" (from Greek "lytikos", meaning able to loosen or dissolve). The word describes a process involving the breaking of a bond in a way that produces different charged species, hence the term 'different breaking'.
Think of 'different' ('hetero-') and 'able to loosen' ('lytic') to remember that 'heterolytic' refers to a type of bond breaking that results in different charged particles.
