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
Act as fabric brightener (by converting ultraviolet light to visible light) thereby improving the whiteness appearance of white fabrics
Attain distinctiveness from other brands
Act as tarnish inhibitor for metals like German silver

Hard glass which is used for making laboratory glass wares is a mixture of sodium borosilicate and aluminium borosilicate
Glass is decolorized during its manufacture by adding antimony oxide, manganese dioxide or arsenic oxide
Ordinary glass is represented chemically by Na2O . CaO . 6SiO2
Red color is imparted to glass by addition of arsenic oxide

It is very corrosive at elevated temperature
Its viscosity is not reduced on further heating (hence pressure drop on pumping it, cannot be further reduced)
It decomposes on further increasing the temperature

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
