CY6151 ENGINEERING CHEMISTRY – I  SYLLABUS (REGULATION 2013)ANNA UNIVERSITY

UNIT I : POLYMER CHEMISTRY

(CY6151) Introduction: Classification of polymers – Natural and synthetic; Thermoplastic and Thermosetting. Functionality – Degree of polymerization. Types and mechanism of polymerization: Addition (Free Radical, cationic and anionic); condensation and copolymerization. Properties of polymers: Tg,
Tacticity, Molecular weight – weight average, number average and polydispersity index. Techniques of polymerization: Bulk, emulsion, solution and suspension. Preparation, properties and uses of Nylon 6,6, and Epoxy resin.

UNIT II : CHEMICAL THERMODYNAMICS 

Terminology of thermodynamics – Second law: Entropy – entropy change for an ideal gas, reversible and irreversible processes; entropy of phase transitions; Clausius inequality. Free energy and work function: Helmholtz and Gibbs free energy functions (problems); Criteria of spontaneity; Gibbs- Helmholtz equation (problems); Clausius-Clapeyron equation; Maxwell relations – Van’t Hoff isotherm and isochore (problems).

UNIT III : PHOTOCHEMISTRY AND SPECTROSCOPY

Photochemistry: Laws of photochemistry – Grotthuss–Draper law, Stark–Einstein law and Lambert – Beer Law. Quantum efficiency – determination- Photo processes – Internal Conversion, Inter-system crossing, Fluorescence, Phosphorescence, Chemiluminescence and Photo sensitization. Spectroscopy: Electromagnetic spectrum – Absorption of radiation – Electronic, Vibrational and rotational transitions. UV-visible and IR spectroscopy – principles, instrumentation (Block diagram only).
