Important Chemistry Chapters for AIIMS BSc Nursing 2027 Entrance Exam

Chemistry 2027 Syllabus for AIIMS BSc Nursing Entrance Exam

AIIMS does not follow a very detailed chapter-wise Chemistry syllabus like other entrance exams do. The entrance exam is usually held at the 10+2/12th standard level. This implies that one should prepare the Chemistry syllabus from NCERT 11th and 12th standard, along with analysing past years’ question papers from the AIIMS BSc Nursing Entrance Exam.

Chemistry can be broadly classified into three topics:

• Physical Chemistry

• Organic Chemistry

• Inorganic Chemistry

One must complete the entire AIIMS BSc Nursing syllabus before proceeding further and then analyse previous years' questions in order to find out chapters which need extra attention.

Important Chemistry Chapters for AIIMS B.Sc. Nursing Entrance Exam 2027

Here are the chapters which are helpful for prioritising your preparation considering the source and the repeated concepts from previous years' analysis. These are not the official AIIMS weightage list.

AIIMS BSc Nursing 2027 Important Chemistry Chapter Details

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, hybridisation, 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 to 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.

Apart from these topics, check Important Chapters for AIIMS BSc Nursing Exam Subject-wise so that you can perform better in all subjects while maintaining equal consistency.

AIIMS BSc Nursing Chemistry Previous Year Questions, Most Expected Questions and Chapter-Wise Weightage

AIIMS BSc Nursing Chemistry previous year questions provide an idea about the frequently asked topics and practice questions in AIIMS entrance exam format. These question papers are not published by AIIMS; rather, these are memory-based and can be prepared through candidates' memory and expert guidance.

Through Career360's analysis of the papers from 2020 to 2026, the following topics under Chemistry have been seen frequently appearing: Chemical Bonding, Coordination Compounds, Organic Reactions, and Biomolecules. Analysis of the memory-based paper 2026 further shows Thermodynamics. These are the trends that one should consider while preparing for the exam.

AIIMS BSc Nursing Chemistry Chapter-Wise Weightage

These are just estimates for preparation purposes. There is no official chapter-wise weightage given by AIIMS. Please do not leave other topics of the syllabus unprepared on the basis of these estimates.

AIIMS BSc Nursing Chemistry Most Expected Questions: Topics to Revise

How to Study Chemistry for AIIMS B.Sc. Nursing Entrance Exam 2027

Given below are some tips which can help you in the effective preparation of the chemistry subject for AIIMS B.Sc. Nursing Entrance Exam 2027.

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.

Chemistry Preparation Strategy for AIIMS BSc Nursing 2027

Strategic preparation of Chemistry can help you score better in the entrance exam for BSc Nursing in AIIMS. Instead of giving equal importance to all chapters, aspirants should focus on high-weightage chapters, solve MCQs, and revise NCERT concepts.

Focus on High-Weightage Chemistry Chapters

Focus on the chapters which are asked frequently in the AIIMS BSc Nursing exam.

• Thermodynamics

• Electrochemistry

• Equilibrium, etc.

Practise MCQs and Previous Year Questions

Including regular AIIMS BSc Nursing Mock Test practice along with Previous year questions can help students gain conceptual clarity and good question-solving speed while understanding the latest exam pattern.

Avoid Studying Too Many Resources

Avoid switching between different books and study materials, especially during the last phase of preparation. Use limited trusted resources for more effective revision.
