Prolonged exposure of fat or oil in moist ,air and light causes bad smell (rancidity). It is due to

A

formation of `C_6- C_12` fatty acids

B

formation of ketone and aldehyde

C

both of these causes

D

formation of glycerol.

Text Solution

Verified by Experts

The correct Answer is:
C
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 .

On exposure to air, alkali metals get tranished due to formation of oxides, hydroxides and carbonates on their surface. When heated in air or oxygen they burn vigourously forming different types of oxides depending upon the nature of the metal. The formation and stability of these metals can be explained on the basis of size of alkali metal ion and the anion. Peroxides are colourless, while superoxides are coloured. The normal oxides are basic while peroxides and superoxides act as oxidising agents. Na_(2)O_(2) has light yellow colour. This is due to
