Content Overview
The exam evaluates various chemical concepts, including ionization energy, molecular structures (e.g., nicotine), thermodynamics of water vapour, and electroactive ions.
It covers advanced topics such as Miller indices, molar conductance, chromatography, spectroscopy (NMR, ESR, IR), Planck's constant, crystal field stabilization energy, and reaction mechanisms.
The assessment includes diverse question formats, such as assertion-reasoning statements, matching exercises, and identification of reaction products or chemical properties.
Topics also extend to industrial and environmental chemistry, such as the pollutant involved in the 1984 Bhopal disaster.
