Symmetry elements and symmetry operations, definitions of group and subgroup, relation between orders of a finite group and its subgroup, conjugacy relation and classes, point group symmetry, Examples of H₂O, NH₃,CH₄ etc.

Atomic Nucleus: mass defect. Nuclear forces: meson exchange theory. Nuclear models (elementary idea): Concept of nuclear quantum number, magic numbers. Natural radioactivity, Radioactive disintegration series, group displacement law, law of radioactive decay, half-life of radio elements. Nuclear Reactions; Artificial radioactivity, transmutation of elements, fission, fusion and spallation. Nuclear energy and power generation. Separation and uses of isotopes. Radio chemical methods: principles of determination of age of rocks and minerals, radio carbon dating, hazards of radiation and safety measures.

Elements of life: Essential, major and trace elements. Basic chemical reactions in the biological systems and the role of metal ions (specially Na⁺, K⁺, Mg²⁺ ,Ca²⁺, Fe^3+/2+ ,Cu^2+/+, and Zn²⁺). Metal ion transport across biological membrane, Na⁺-ion pump, ionophores.

Biological functions of hemoglobin and myoglobin, cytochromes and ferredoxins, carbonate -bicarbonate buffering system and carbonic anhydrase. Biological nitrogen fixation, Photosynthesis: Photosystem-I and Photosystem-II.

Molecular recognition: molecular receptors for different types of molecules including arisonic substrates, design and synthesis of coreceptor molecules and multiple recognition.

General principles, experimental procedures, co-precipitation as a precursor to solid state reactions, kinetics of solid state reactions. Preparative methods of inorganic solids (sol,gel   MOCVD processes) – crystallization of solutions, glasses, gels and melts, vapour phase transport methods, electrochemical reduction methods, preparation of thin films, growth of single crystals, high pressure and hydrothermal methods.
