The first order dependence on oxidant as well as
substrate concentration shows that perhaps the comꢀ
plex formation between them is not feasible or the so
formed complex can be presumed as fragile in nature.

(
1) In the presence of acid, both ketone and HOCl
are protonated.
2) The added chloride ions react with H OCl+
protonated form of HOCl) to form chlorine which
further form a complex with protonated ketone in a
rate determinating step.

Hence, even in the absence of chloride ions, the
final products of oxidation of cyclopentanone, cycloꢀ
hexanone, cycloheptanone and cyclooctanone are
glutaric, adipic, pimelic and suberic acids, respecꢀ
