Introduction
Hydrogen is one of the most important chapters of Inorganic Chemistry for JEE Main aspirants. Despite being a short chapter, questions from Hydrogen are regularly asked in the exam. Practising Hydrogen JEE Main PYQs (Previous Year Questions) helps students understand the exact level, pattern, and concept depth required to score well in the Chemistry section.
Why Hydrogen is Important for JEE Main
Hydrogen connects multiple areas of Chemistry such as atomic structure, chemical bonding, thermodynamics, and redox reactions. Due to its wide application and conceptual nature, JEE Main frequently includes direct and indirect questions from this chapter.
- Simple theory-based questions are often asked
- Concepts are scoring and less time-consuming
- PYQs are repetitive in nature
- Helpful in strengthening Inorganic fundamentals
Trend of Hydrogen PYQs in JEE Main
On average, 1–2 questions are asked every year from the Hydrogen chapter in JEE Main. Most questions are direct and concept-based, making this chapter highly scoring if prepared properly.
Commonly asked question formats include:
- Multiple-choice conceptual questions
- Assertion–Reason type questions
- Reaction-based product identification
- Statement-based conceptual questions
Important Topics from Hydrogen Chapter
1. Isotopes of Hydrogen
Questions are frequently asked on protium, deuterium, and tritium, focusing on their physical properties, uses, and differences.
2. Dihydrogen (Hâ‚‚)
Preparation methods, physical and chemical properties, and applications of hydrogen as a fuel and reducing agent are important areas.
3. Hydrides
Understanding different types of hydrides is crucial:
- Ionic hydrides
- Covalent hydrides
- Interstitial (metallic) hydrides
4. Water and Hydrogen Peroxide
Reactions, structure, oxidising and reducing nature of hydrogen peroxide are frequently tested in JEE Main PYQs.
5. Industrial and Practical Applications
Industrial preparation of hydrogen, water gas shift reaction, and its role in chemical industries are also important from an exam point of view.
How to Use Hydrogen PYQs Effectively
Solving previous year questions is one of the smartest preparation strategies. Hydrogen PYQs help students identify repeated concepts and improve exam confidence.
- Solve PYQs after completing theory
- Mark frequently repeated questions
- Revise weak areas immediately
- Practice time-bound question solving
Study Strategy for Hydrogen Chapter
- Day 1: Revise theory and NCERT examples
