Chemistry of Metals :
General principles of metallurgy – occurrence, concentration of ores, production and purification of metals, mineral wealth of India.
Typical metals (Na, Ca, Al, Fe, Cu and Zn) – occurrence, extraction, purification (where applicable), properties and reactions with air, water, acids and non-metals.
Manufacture of steels and alloy steel (Bessemer, Open-Hearth and L.D. process).
Principles of chemistry involved in electroplating, anodizing and galvanizing.
Origin, Evolution and Diversity of Life : Haldane and Oparin’s concept on origin of life. Modern concept of Natural selection, Biological Species concept.
