  • Atomic structure

     Discovery of subatomic particles (electron, proton, and neutron). Thomson and Rutherford atomic models and their limitations.  Nature of electromagnetic radiation, photoelectric effect.  The spectrum of hydrogen atom, Bohr model of hydrogen atom – its postulates, derivation of the relations for energy of the electron and radii of the different orbits, limitations of Bohr’s model.  Dual nature of matter, de-Broglie relationship, Heisenberg uncertainty principle.  Elementary ideas of quantum mechanics, the quantum mechanical model of an atom, its important features, the concept of atomic orbitals as one electron wave functions.  Variation of Ψ1 and Ψ2 with r for 1s and 2s orbitals; various quantum numbers (principal, angular momentum, and magnetic quantum numbers), and their significance.  Shapes of s, p and d – orbitals, electron spin and spin quantum number.  Rules for filling electrons in orbitals – Aufbau principle, Pauli exclusion principle and Hund’s rule, electronic configuration of elements, the extra stability of half-filled and completely filled orbitals

  • Organic nomenclature

     Tetravalency of carbon; Shapes of simple molecules – hybridization (s and p).  Classification of organic compounds based on functional groups: -C = C- and those containing halogens, oxygen, nitrogen, and sulfur; Homologous series.  Isomerism: structural and stereoisomerism  Nomenclature (Trivial and IUPAC): Covalent bond fission Homolytic and heterolytic: free radicals, carbocations, and carbanions; stability of carbocations and free radicals, electrophiles and nucleophiles.  Electronic displacement in a covalent bond: Inductive effect, electromeric effect, resonance, and hyperconjugation.  Common types of organic reactions: Substitution, addition, elimination, and rearrangement.
