DDT is manufactured by the condensation of chlorobenzene with chloral at 30°C in presence of oleum, which is a highly exothermic reaction
Chloral is obtained by the chlorination of ethyl alcohol
Insecticides acting on the insects through the respiratory system are called fumigants
Benzene hexachloride is not a contact insecticide
Catalytic hydrogenation of carbon monoxide produces methyl alcohol
In nylon-6, the number 6 represents the total number of carbon atoms in the ring
Raw materials for DDT manufacture are benzene and chlorine
Ethanolamines are produced by using ammonia and ethylene oxide as raw material

A fat is converted into oil by its hydrogenation
There is no difference between a fat and an oil so far as its physical properties are concerned
All vegetable oils except coconut oil, contains fatty acids having more than sixteen carbon atoms
Vegetable oils are classified as drying, non-drying and semi drying oils depending upon their fatty acids content
