Chemistry — Model Syllabus Roadmap

22 Official 2024 Lecturer Disciplines — Syllabus Directory · Subjects 1–11

Useful for: SSB Lecturer (Degree Colleges)

Overview

Postgraduate chemistry spans physical, inorganic, organic and analytical chemistry.

Key points

Physical: thermodynamics, kinetics, quantum chemistry, spectroscopy.
Inorganic: periodicity, coordination chemistry (Werner’s theory), organometallics.
Organic: reaction mechanisms (SN1, SN2, E1, E2), stereochemistry, synthesis.
Analytical: titrimetry, chromatography, instrumental methods.
Spectroscopy: UV-visible, IR, NMR, mass spectrometry.
Green chemistry and environmental chemistry.

Explanation

SN2 reactions proceed with inversion of configuration (Walden inversion).
Hund’s rule governs electron filling in degenerate orbitals.
Crystal field theory explains colour of complexes.
NMR identifies hydrogen environments.

Step by step

Place the question in its unit of the syllabus.
Recall the theory, thinker, law or work involved.
Eliminate options from other schools, periods or units.

Examples

Inversion of configuration → SN2.
Coordination theory → Alfred Werner.
Technique identifying functional groups by vibrations → IR spectroscopy.

Traps and advanced points

Trap: Mixing SN1 and SN2 outcomes.
Trap: Wrong spectroscopy use.
Trap: Ignoring stereochemistry.

Quick revision

Four branches.
SN2 inversion.
Werner; spectroscopy.
