Is the GATE Chemistry syllabus subject to change?

The core subjects of the GATE Chemistry syllabus remain relatively stable. However, it's important to check the official GATE website for any updates or changes in the syllabus before starting your preparation.

Are there any specific topics within each subject that are more important for GATE Chemistry?

While the entire syllabus is important, some topics carry more weightage than others. For example, in Physical Chemistry, topics like thermodynamics, chemical equilibrium, and quantum mechanics are crucial.

In Organic Chemistry, topics like reactions of organic compounds, stereochemistry, and organic synthesis are significant. In Inorganic Chemistry, topics like coordination compounds, periodic table, and chemical bonding hold importance.

What is the exam pattern for GATE Chemistry?

The GATE Chemistry exam consists of a total of 65 questions, with a duration of 3 hours. The question paper is divided into two sections: Multiple Choice Questions (MCQs) and Numerical Answer Type (NAT) questions.

MCQs carry 1 or 2 marks each, while NAT questions carry 1 or 2 marks each. There is negative marking for incorrect answers in MCQs.

Is there a specific weightage assigned to each subject in the GATE Chemistry exam?

No, there is no specific weightage assigned to each subject. The distribution of questions can vary from year to year.

However, it is generally observed that questions related to all three subjects - Physical Chemistry, Inorganic Chemistry, and Organic Chemistry - have a presence in the exam.

Are there any recommended books or resources to cover the entire GATE Chemistry syllabus?

Some popular books for GATE Chemistry preparation include 'Physical Chemistry' by P. Bahadur, 'Inorganic Chemistry' by J.D. Lee, 'Organic Chemistry' by Morrison and Boyd, and 'Numerical Chemistry' by P. Bahadur. Additionally, previous years' question papers and study materials from reputed coaching institutes can be helpful.

Are there any specific reference books for numerical problem-solving in GATE Chemistry?

Yes, there are books available that focus on numerical problem-solving in Chemistry. 'Numerical Chemistry' by P. Bahadur is a popular choice for practicing numerical problems in Physical Chemistry.

Is it necessary to study Mathematics for the GATE Chemistry exam?

Yes, Mathematics is an integral part of the GATE Chemistry syllabus. Topics such as calculus, differential equations, linear algebra, and numerical methods are included.

It's essential to allocate sufficient time for studying and practicing mathematics concepts.

Are there any online resources or mock tests available for GATE Chemistry preparation?

Yes, there are several online platforms and websites that offer free and paid resources for GATE Chemistry preparation. Some popular ones include Unacademy, Khan Academy, and GateForum.

These platforms provide study materials, video lectures, mock tests, and previous years' question papers.

Is practical knowledge important for the GATE Chemistry exam?

While the GATE Chemistry exam primarily focuses on theoretical knowledge, practical understanding of concepts can be beneficial. Practical experience can help in

    • Hello Gaurav,

      At present we do not have any certain info. If we find any we will notify you as soon as possible.

      Feel free to ask if you need any help in future & join us @ Google+ / Facebook for getting regular updates.

  1. Hello sir
    I’ve done graduation with chemistry (6.75 CGPA) and PG with Industrial Chemistry (7.27 CGPA)
    Industrial chemistry is 70% chemical engineering + 30% chemistry

    So in GATE, which paper should I opt so that PSUs like ONGC,IOCL consider me eligible for an interview call ?

    I’m in big confusion because my graduation and PG is not exactly in same course.
    I want job in PSUs like ONGC and IOCL
    Please guide me sir…..

    Thank you.

    • Hello Jayyesh ,

      You can choose a subject for GATE paper which is closely related to your masters(non-engineering candidates) / closely related to your bachelor(engineering candidates).
      Here we need to know two things :
      1. You are engineering graduate or non-engineering graduate ?
      2. What option(s) you want to choose for GATE paper ?

      Feel free to ask if you need any help in future & join us @ Google+ / Facebook for getting regular updates.
