Secondary alcohols are oxidised to ketones by chromic anhyride
(CrO3) Tertiary alcohols do not undergo oxidation reaction Under strong
reaction conditions such as strong oxidising agents (KMnO4) and
elevated temperatures, cleavage of various C-C bonds takes place
and a mixture of carboxylic
acids containing lesser number
of carbon atoms is formed When the vapours of a
primary or a secondary alcohol
are passed over heated copper
at 573 K, dehydrogenation
takes place and an aldehyde or
a ketone is formed while tertiary
alcohols undergo dehydration
