Prolonged exposure of fat or oil in moist air and light causes bad smell (rancidity). It is due to
formation of C6 - C12 fatty acids
formation of ketone and aldehyde
both of these causes
formation of glycerol.
C.
both of these causes
On long storage in contact with air and moisture, oils and fats develop unpleasant smell.
This process is known as ranicidification. It is due to
(a) Enzymatic hydrolysis - producing bad smelling lower fatty acids.
(b) Oxidation of unsaturated acids - producing aldehydes and ketones.
Cumene process is the most important commercial method for the manufacture of phenol. Cumene is
iso-propyl benzene
ethyl benzene
vinyl benzene
propyl benzene.
