(iii) Oxidation of methyl ketones by haloform reaction:
Aldehydes and ketones having at least one methyl group
linked to the carbonyl carbon atom (methyl ketones)
are oxidised by sodium hypohalite to sodium salts of
corresponding carboxylic
acids having one carbon
atom less than that of
carbonyl compound The
methyl 
group 
is
converted to haloform This oxidation does not
affect a carbon-carbon
double bond, if present
in the molecule Iodoform reaction with sodium hypoiodite is also used for detection
of CH3CO group or CH3CH(OH) group which produces CH3CO group
on oxidation
