This article provides a list of high-weightage Chemistry chapters for AIIMS BSc nursing 2026 that carry more marks in the exam. Students can also check the detailed Chemistry syllabus with key points, formulas, and tips to remember. All chapters are based on NCERT and aligned with the official exam pattern to ensure effective preparation.
Chemistry is a major part of the AIIMS B. Sc Nursing Entrance Examination. It checks your fundamentals and application-based problem-solving skills, mainly from the 11th and 12th-grade syllabus. Doing the important chapters of Chemistry will help one get good marks in the examination.
An overview of the AIIMS BSc nursing syllabus has to be done before looking into the most important chapters. AIIMS BSc nursing Chemistry is based on the NCERT syllabus. The important topics of physical, inorganic, and organic chemistry are covered in this subject.
The table given below shows the important Chemistry chapters and the key Chemistry topics to focus on:
Important Chapters | Key Topics |
Periodic Table, electron configuration, and quantum numbers. | |
Types of bonds, hybridisation, and structure of molecules. | |
Chemical reactions, enthalpy, and entropy. | |
Hydrocarbons, functional groups, and reaction mechanisms. | |
Le Chatelier's principle, pH and solubility product. |
The following are some important chapters for AIIMS B.Sc. Nursing exam that every aspirant should study in detail:
Atomic Structure
The atomic structure forms the foundation of Chemistry. The Bohr model, quantum numbers, electron configuration, and isotopes need to be covered. Note subatomic particles: properties and how these influence chemical behaviour.
Chemical Bonding and Molecular Structure
It covers ionic, covalent, and metallic bonds. It commonly includes concepts such as VSEPR theory, hybridization, and molecular orbital theory and has often been asked in the AIIMS B.Sc. Nursing exam.
Thermodynamics
Thermodynamics is a fundamental chapter, and students need to know the laws of thermodynamics, enthalpy, entropy, and Gibbs free energy. All these laws are applied based on chemical reactions, so one needs to emphasise this more in this chapter.
Equilibrium
Chemical and ionic equilibrium are chapters of great importance, and one needs to understand the concept of an equilibrium constant, Le Chatelier's principle, and the pH calculation concept. Buffer solutions acids and bases are commonly asked questions.
Redox Reactions
This chapter deals with oxidation-reduction reactions, balancing redox reactions, and understanding the concepts of oxidation number and electrode potential. Mastery of the basic concepts will allow you to solve questions on this topic with ease.
Solutions
From the characteristics of solutions to solubility, concentration terms, molarity, molality, and colligative properties-this chapter is a crucial one. Many AIIMS B.Sc. Nursing questions relate to Raoult's law and the van Hoff factor.
Electrochemistry
Another important high-weightage topic is that of electrochemistry. Galvanic and electrolytic cells come under this, along with the Nernst equation, conductance, and the working of electrochemical cells. Faraday's laws of electrolysis are asked very often, so give them ample importance.
Chemical Kinetics
Chemical kinetics pertains to the study of reaction rates and what factors influence such reaction rates. Some questions in this chapter will be solved if you have understood rate laws, activation energy, and collision theory.
Organic Chemistry: Principles and Techniques
Organic Chemistry is an important constituent of the AIIMS B.Sc. Nursing entrance examination. Students should stress more on the classification of organic compounds, isomerism, and reaction mechanisms like nucleophilic substitution and electrophilic addition reactions.
Hydrocarbons
This chapter will deal with alkanes, alkenes, alkynes, and aromatic hydrocarbons. Their preparation, properties, and reactions should be well known since questions are very often asked from this portion.
Alcohols, Phenols and Ethers
It is essential to learn about the preparation and reactions of alcohols, phenols, and ethers, considering their properties and chemistry, like acidity, dehydration, and oxidation reactions.
Aldehydes, Ketones, and Carboxylic Acids
The properties and reactions of aldehydes, ketones, and carboxylic acids have posed many questions in the entrance test. Attention should be given to topics such as nucleophilic addition reactions and oxidation of aldehydes.
Biomolecules
Biomolecules constitute an important chapter, especially in any nursing entrance like AIIMS B.Sc. Nursing. Carbohydrates, proteins, lipids, vitamins, and nucleic acids have important structures and functions that need to be known in detail.
Given below are some tips which can help you in the effective preparation of the chemistry subject for AIIMS B.Sc. Nursing Entrance Examination.
Understand the Concepts
Chemistry requires a sound conceptual understanding of the subject. Always focus on learning the core principles rather than mere memorisation.
Practice Numerical Problems
Many topics in Physical Chemistry are based on numerical problems. Regular practice of questions from some standard topics like chemical kinetics, thermodynamics, and equilibrium helps you increase your speed and accuracy.
Focus on Organic Chemistry Reactions
This branch of chemistry is feared by many students. However, one should know the complete reaction mechanism, named reactions, and functional group interconversions of Organic Chemistry.
Previous Years' Paper Solutions
Certain types of questions are repeatedly asked in the AIIMS B.Sc. Nursing entrance examination. You can solve aiims bsc nursing previous year question papers to get an idea about the pattern of the examination and important topics.
Revise Regularly
Regular revision is the only way to remember important Chemistry concepts and formulae. Just keep revising the important chapters mentioned above to obtain a high score in the examination.
On Question asked by student community
Hello,
AIIMS B.Sc Nursing entrance exam ka syllabus NCERT Class 11–12 par based hota hai. Agar CBSE ya state board ne kuch chapters delete kiye hai, to bhi AIIMS apne original NCERT syllabus se hi questions pooch sakta hai. Deleted syllabus se questions aane ke chances hote hai, kyunki AIIMS board-wise reductions follow nahi karta. Isiliye aapko pura NCERT 11–12 syllabus complete padhna hoga, deleted chapters bhi.
Hope it helps!!!
Hello there!
Yes both boys and girls can apply for AIIMS nursing entrance exam. Both boys and girls should meet the same eligibility criteria.
Thank you
Hello aspirant,
An excellent resource for test preparation is the AIIMS BSc Nursing Previous Year Question Papers.

Hello,
If you are getting ready for the AIIMS B.Sc. Practicing previous year question papers (PYQs) for the nursing entrance exam is among the most efficient methods to grasp the exam structure, level of difficulty, and key topics. Although AIIMS does not officially provide all its nursing previous year questions (PYQs), you can still access compiled papers and sample papers from reliable publishers, nursing entrance preparation books, or educational websites such as Arihant, MTG, or online forum like Careers360.
Hope this helps. All the best!
