Which topic is very important for the CSIR NET for chemical science?

Greetings and regards from Bansal Academy! Thank you for your question regarding important topics for CSIR NET in Chemical Science.

In CSIR NET Chemical Science, it is essential to cover a wide range of topics to ensure comprehensive preparation. However, some topics are often considered crucial due to their frequent inclusion in the exam. Here are some important topics for CSIR NET Chemical Science:

Knowing the syllabus plays an important role during the preparation. The chemical science syllabus is very vast and it is not needed to cover the whole syllabus. We can crack the CSIR NET chemical science if we focus on the important topics only. Let’s look at the important topics of chemical science mentioned below:

The syllabus of chemical science is divided into 4 sections:

• Inorganic Chemistry

• Organic Chemistry

• Physical Chemistry

• interdisciplinary Topics

1. Important Topics from Inorganic Chemistry

• Structure and bonding in homo- and heteronuclear molecules, including shapes of molecules (VSEPR Theory). Weightage: 7%

• Main group elements and their compounds: Allotropy, synthesis, structure and bonding, industrial importance of the compounds. Weightage: 10%

• Transition elements and coordination compounds: structure, bonding theories, spectral and magnetic properties, reaction mechanisms. Weightage: 15%

• Organometallic compounds: synthesis, bonding and structure, and reactivity. Organometallics in homogeneous catalysis. Weightage: 15%

• Characterisation of inorganic compounds by IR, Raman, NMR, EPR, Mössbauer, UV-vis, NQR, MS, electron spectroscopy and microscopic techniques. Weightage: 8%

2. Important Topics from Physical Chemistry

• Common named reactions and rearrangements – applications in organic synthesis. Weightage: 14%

• Organic transformations and reagents: Functional group interconversion including oxidations and reductions; common catalysts and reagents (organic, inorganic, organometallic and enzymatic). Chemo, regio and stereoselective transformations. Weightage: 14%

• Pericyclic reactions – electrocyclisation, cycloaddition, sigmatropic rearrangements and other related concerted reactions. Principles and applications of photochemical reactions in organic chemistry. Weightage: 14%

• Structure determination of organic compounds by IR, UV-Vis, 1H & 13C NMR and Mass spectroscopic techniques. Weightage: 12%

It's important to note that the CSIR NET Chemical Science syllabus is extensive, and candidates should strive for a balanced understanding of all topics. Regular practice of numerical problems, theoretical concepts, and solving previous year papers will contribute significantly to exam preparation.
