Physical Organic Chemistry

This course introduces the concept of reaction coordinates and energy profiles in chemical reactions. It explains the differences between transition states and reaction intermediates and how these are represented in reaction coordinate diagrams. The course also covers thermodynamic and kinetic control of reactions and provides a qualitative understanding of the Hammond Postulate. By the end of the course, students will be able to interpret reaction energy diagrams and understand factors that influence reaction pathways and product formation.

ORGNIC RECTION MECHANISM-DR SUPRABHA S

This course covers the electron displacement effects in organic chemistry, including the inductive effect, electromeric effect, mesomeric effect, resonance, hyperconjugation, and steric effect, which explain how electrons shift within molecules and influence their stability and reactivity. It also discusses the acidity and basicity of organic compounds based on these effects, focusing on the acidic nature of alcohols, phenols, and carboxylic acids, and comparing compounds such as phenol, o/m/p-cresols, o/m/p-nitrophenols, aliphatic acids, mono-, di- and trichloroacetic acids, benzoic acid, and o/m/p-nitrobenzoic acids. The course further examines the basic character of amines, including aliphatic amines, aniline, and N- and N,N-dimethyl aniline. In addition, it explains the effects of hyperconjugation on the stability of alkenes, alkylbenzenes, free radicals, and carbocations, along with its role in the dipole moments of propene and toluene. Finally, the course introduces important reaction intermediates such as carbocations, carbanions, carbenes, and nitrenes, covering their definitions, hybridization, structures, classification, formation, stability, and examples, which are essential for understanding organic reaction mechanisms.
