SYLLABUS- ENGINEERING CHEMISTRY,
Unit-I: Introduction of Engineering Chemistry
Atoms to Molecules to Materials for Engineers: Atoms combines to give molecules and how
molecules aggregate o give materials.
Recapitulation of salient feature of valence bond theory, Hybridization, sigma and pi shape of the
simple inorganic compounds based upon concepts of hybridization and to illustrate planar, tetrahedral
square, and octahedral geometries.
Molecular orbital theory and its application to form homo (H2, N2 & O2) and hetero (HF, NO)
diatomic molecules.
Structure and Stereo Structure of Molecules: Representing three dimensional structure of organic
molecules including Conformations, Newman, Sawhorse, Fischer, projections wedge and dash
structural representation, equivalence of structural representations.
Chirality, optical activity and isomerism, compounds containing one and two chiral carbons,
enantiomers, distereo isomers, meso compounds, no. of chiral atoms and optical isomers, Dynamic
stereochemistry, concepts of regiochemistry, stereo selectivity, stereo specificity and enantiomeric
excess R&S nomenclature.

Unit-II: Materials and their Characterization
Micro and macroscopic properties of molecules Intermolecular forces, Molecular aggregation
micelles. Examples of inorganic and organic functional materials, core concepts of nanotechnology.
Purification: Physical (crystallization, fractional crystallization, distillation, fractional distillation,
steam distillation) and chemical methods of purification. General chromatographic (Adsorption and
partition) techniques (column thin layer and paper chromatography) and their application.
Criteria of Purity: Melting and Boiling point, chromatography, particle size measurement and
surface area.
Characterization:Surface tension, Viscosity, Conductivity and Absorption Spectroscopy (IR, UV -
Visible, NMR).

reactions, pseudo first order reaction, temperature dependence of reaction rates, Catalysis and some
industrially importance catalytic reactions.

SNAr) and electrophilic substitution reactions (Nitratation, Sulphonation, Halogenation, and Friedel
Crafts reaction) and their mechanism, regio and Stereochemistry of involved reactions.
