CHM101: Chemistry of elements and chemical transformations

        [Cr:3, Lc:2, Tt:1, Lb:0]

Course Outline

• Periodic table and periodicity of properties (atomic & ionic radius, electronegativity, electron affinity, ionization energy). Concept of effective nuclear charge. Electronic configuration of main group elements, transition metals, lanthanides & actenides.
• Main group elements: (i) Discussion of physical parameters & chemical properties (hydrides, oxides, halides) and their periodicity. (ii) Some unusual properties of heavy post-transition elements and their rationalization. (iii) Group-wise discussion of s-block and p-block elements covering their oxides, oxoacids, halides, hydrides, silicates, silicones, borazine, P-N & S-N compounds, polyhalides, pseudo-halogens, interhalogens and halogen cations.
• Transition elements: Nomenclature and isomerism of coordination compounds. Theories of bonding (VBT & CFT of octahedral, tetrahedral & square planar geometries). Electronic transitions (intraligand, d-d & charge transfer) & magnetic behaviour.
• Nomenclature of organic compounds. Reaction mechanism (concept of electronic and steric effects). Stereochemistry: Conformational analysis of acyclic (ethane & butane) and cyclic (cyclohexane) systems. Energies of differently substituted dimethylcyclohexanes. Chirality R & S assignment. Molecules with two stereogenic centers: eryhtro, threo, meso and d,l- racemates.
• Reaction types:
  1. Substitution reactions: Nucleophilic substitution at $sp^3$ carbon and its mechanism Addition reactions: Addition of X${}_2$, HX, boranes and hydroxylation to C=C systems.
  2. Elimination reactions: Elimination reactions leading to C=C bond formation and their mechanisms. Hoffman and Saytzeff elimination.
