For every medical or engineering aspirant in India, the NCERT textbooks are often hailed as the "Holy Grail." While this reputation is well-deserved—especially for NEET and JEE Main—the narrative changes significantly when you aim for a top-tier rank or prepare for the rigors of JEE Advanced.
The truth is, NCERT is designed to provide a conceptual foundation. However, competitive exams often test the application of these concepts in complex, multi-layered scenarios that the textbook barely touches upon. In this blog, we will identify the specific topics in Inorganic and Physical Chemistry where NCERT falls short and guide you on the reference books needed to bridge that gap.
1. Physical Chemistry: Moving Beyond Formulas
In Physical Chemistry, NCERT provides the definitions and basic formulas. However, the exam demands a level of mathematical proficiency and "problem-solving intuition" that requires extensive practice.
The Missing Links in NCERT:
Atomic Structure: NCERT introduces Quantum Numbers and the Bohr Model, but it lacks depth in Schrödinger’s Wave Equation and the graphical interpretation of probability density functions ($|\psi|^2$).
Thermodynamics: While the laws are explained, the application of Gibbs Free Energy in non-standard conditions and the mastery of complex PV diagrams (Thermochemistry) often require external help.
Ionic Equilibrium: This is arguably the toughest chapter for many. NCERT’s coverage of Buffer Solutions, Salt Hydrolysis, and Solubility Product is too brief for the variety of "mixed salt" problems asked in JEE Advanced.
Electrochemistry: The Nernst Equation is there, but the advanced calculation of Liquid Junction Potential or the depth of Corrosion and Electrolysis mechanics is insufficient.
Recommended Reference Books:
For Numericals: P. Bahadur or Narendra Avasthi. These books offer a tiered approach to problems, starting from basic to advanced levels.
For Conceptual Clarity: O.P. Tandon or R.C. Mukherjee (specifically for Modern Approach to Chemical Calculations).
2. Inorganic Chemistry: The Logic Behind the Rote
Inorganic Chemistry is often dismissed as "purely memorization." NCERT is excellent for facts, but it frequently omits the "Why" behind the "What." Without the underlying logic, memorizing hundreds of reactions becomes nearly impossible.
The Missing Links in NCERT:
Chemical Bonding: NCERT covers VSEPR and Molecular Orbital Theory (MOT). However, it doesn't go deep into Back Bonding, Bridge Bonding, and Fajan’s Rule—all of which are favorite topics for examiners.
Coordination Compounds: While it introduces Crystal Field Theory (CFT), it lacks a detailed explanation of Jahn-Teller Distortion or the magnetic properties of complex high-spin/low-spin transitions.
Qualitative Analysis (Salt Analysis): This is the biggest gap. NCERT doesn't have a dedicated chapter for Salt Analysis, yet it is a high-weightage topic. You must refer to lab manuals or specialized books for this.
p-Block Elements: NCERT has a lot of data, but the structural chemistry of Silicates, Phosphates, and Oxoacids is much better explained in reference texts.
Recommended Reference Books:
The Bible of Inorganic: J.D. Lee (Concise Inorganic Chemistry). It provides the reasoning and structural depth missing in NCERT.
For Practice: V.K. Jaiswal. This is essential for practicing MCQs that follow the latest exam patterns.
3. Comparison Table: NCERT vs. Reference Books
Feature | NCERT Chemistry | Reference Books (e.g., J.D. Lee, P. Bahadur) |
Conceptual Depth | Foundational; focuses on "what." | Advanced; focuses on "why" and "how." |
Numerical Practice | Very limited; mostly basic. | Thousands of problems; varied difficulty levels. |
Logical Reasoning | Often skipped in favor of facts. | Explains exceptions and structural anomalies. |
Salt Analysis | Minimal coverage. | Detailed schemes for ion identification. |
Suitability | Best for Boards & NEET. | Essential for JEE Advanced top ranks. |
FAQs
Q1. Can I skip NCERT if I am using reference books?
No. Never skip NCERT. It is the "base" of the pyramid. Reference books should be used to build upon the foundation NCERT provides, not replace it. Many questions in JEE Main and NEET are still lifted directly from NCERT lines.
Q2. Which reference book is best for Physical Chemistry numericals?
For sheer volume and variety of problems, Narendra Avasthi is currently the most popular choice among toppers. For learning how to approach a calculation, R.C. Mukherjee is unparalleled.
Q3. How do I study Inorganic Chemistry without getting bored?
Instead of just reading NCERT, use a reference book like J.D. Lee to understand the logic (like Effective Nuclear Charge or Steric Hindrance). Once you understand the reason for a trend, you won't need to "mug it up."

Conclusion
NCERT is undoubtedly the most important book in your arsenal, but it is not the only book you need. To truly master Inorganic and Physical Chemistry, you must be able to solve complex numericals and understand the structural "why" behind chemical behavior. Use NCERT as your map, but let reference books be your guide through the difficult terrain of competitive exams.
