Subject-wise and section-wise marks in the IIT JAM Chemistry answer key

The IIT JAM (Joint Admission Test for M.Sc.) is a national level entrance exam conducted by the Indian Institutes of Technology (IITs) for admission to various postgraduate courses in science and technology. The Chemistry paper of IIT JAM consists of multiple-choice questions (MCQs) and is divided into three sections: Physical Chemistry, Organic Chemistry, and Inorganic Chemistry.

Subject-wise marks distribution:

The subject-wise marks distribution for the Chemistry paper in IIT JAM may vary from year to year. However, on average, the marks distribution is as follows:

1. Physical Chemistry: This section generally focuses on topics like thermodynamics, chemical kinetics, quantum mechanics, and spectroscopy. It carries around 30-35% weightage in the Chemistry paper.

2. Organic Chemistry: This section primarily covers topics like organic reactions, stereochemistry, and organic synthesis. It carries around 30-35% weightage in the Chemistry paper.

3. Inorganic Chemistry: This section mainly deals with topics like coordination chemistry, periodic table and chemical bonding, and analytical chemistry. It carries around 30-35% weightage in the Chemistry paper.

Section-wise marks distribution:

Within each section, the IIT JAM Chemistry paper is further divided into sub-sections or topics. The marks distribution for each sub-section may vary, but some common sub-sections and their weightages are:

1. Physical Chemistry:
- Thermodynamics: 8-10 marks
- Chemical Kinetics: 6-8 marks
- Quantum Mechanics and Spectroscopy: 10-12 marks

2. Organic Chemistry:
- Organic Reactions: 8-10 marks
- Stereochemistry: 6-8 marks
- Organic Synthesis: 10-12 marks

3. Inorganic Chemistry:
- Coordination Chemistry: 8-10 marks
- Periodic Table and Chemical Bonding: 6-8 marks
- Analytical Chemistry: 10-12 marks

It is important to note that the exact marks distribution for each sub-section may vary in different years of the IIT JAM Chemistry paper. Therefore, it is advisable to refer to the official answer key released by the conducting authority to get the accurate subject-wise and section-wise marks distribution for each question.

In conclusion, the subject-wise marks distribution in the IIT JAM Chemistry paper is generally divided into Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. Each section carries around 30-35% weightage. Within each section, the paper is further divided into sub-sections, and the marks distribution for each sub-section may vary. It is recommended to refer to the official answer key for the precise details of subject-wise and section-wise marks for each question in the IIT JAM Chemistry paper.
