About Elementary Problems in Organic Chemistry
Elementary Problems in Organic Chemistry by M.S. Chouhan is an indispensable tool for medical and engineering aspirants. While many organic chemistry books focus entirely on tough, obscure reactions, this “Elementary” version focuses strictly on the core syllabus, making it highly relevant for NEET and JEE Main.
Published by Shri Balaji Publications, the book is designed to help students master reaction mechanisms through extensive objective-type practice. It forces students to recognize electrophiles, nucleophiles, and reaction intermediates instead of just memorizing final products.
The defining feature of this book is its graded multiple-choice questions that cover every possible variation of standard reactions found in the NCERT curriculum. This allows a student to grow their confidence organically, ensuring they don’t make silly errors in highly competitive exams.

Hydrocarbons & Halides
Core reactions: Alkanes, Alkenes, Alkynes, and Haloalkanes/Haloarenes.
Oxygen Compounds
Application-heavy topics: Alcohols, Phenols, Ethers, Aldehydes, Ketones, and Carboxylic Acids.

High-scoring end topics: Amines, Biomolecules, and Polymers.
Block 1: Basics & GOC
⬇ Download MS Chouhan Elementary PDFThis block sets the absolute foundation for all organic chemistry. A weak grasp of GOC and Isomerism will make every subsequent chapter impossible to understand. M.S. Chouhan provides exceptional practice here to ensure absolute accuracy in identifying stability, acidity, basicity, and chiral centers.
Chapters and Subtopics
- IUPAC Nomenclature: Naming of complex branched chains, functional groups, bicyclo, and spiro compounds.
- Isomerism: Structural isomerism, geometrical (cis-trans, E-Z), optical isomerism, enantiomers, diastereomers, and meso compounds.
- General Organic Chemistry (GOC): Inductive effect, resonance, hyperconjugation, aromaticity, carbocations, carbanions, and acid-base strength comparison.
Block 2: Hydrocarbons & Halides
This is where reaction mechanisms begin in full force. The sheer volume of questions ensures that students stop memorizing and start understanding how electrons flow from electron-rich to electron-poor sites.
Chapters and Subtopics
- Hydrocarbons: Preparation and properties of Alkanes (free radical substitution), Alkenes (electrophilic addition, Markovnikov’s rule), Alkynes, and Benzene (Electrophilic Aromatic Substitution).
- Haloalkanes & Haloarenes: Nucleophilic substitution (SN1, SN2, SNi), Elimination reactions (E1, E2, E1cb), Saytzeff vs. Hofmann products, and Grignard reagents.
Block 3: Oxygen Containing Compounds
These chapters form the bulk of the Class 12 organic chemistry syllabus. They are highly scoring because the question patterns are relatively standard, provided the student has practiced enough to recognize the reagents instantly.
Chapters and Subtopics
- Alcohols, Phenols & Ethers: Dehydration, oxidation of alcohols, Reimer-Tiemann reaction, Kolbe’s reaction, and cleavage of ethers.
- Aldehydes & Ketones: Nucleophilic addition, Aldol condensation, Cannizzaro reaction, Haloform reaction, and various reduction methods (Clemmensen, Wolff-Kishner).
- Carboxylic Acids & Derivatives: Acidity trends, esterification, HVZ reaction, and hydrolysis of amides/esters.
Block 4: Nitrogen Compounds & Biomolecules
The final block contains Nitrogen compounds, which heavily rely on basicity concepts from GOC. Biomolecules and Polymers provide a lighter, more theoretical balance that requires repeated practice to memorize standard structures.
Chapters and Subtopics
- Amines & Diazonium Salts: Basicity of amines, Gabriel phthalimide synthesis, Hofmann bromamide degradation, and coupling reactions.
- Biomolecules: Carbohydrates (glucose, fructose structures), Amino acids (isoelectric point, zwitterion), Proteins, and Nucleic acids.
- Polymers & Everyday Life: Addition vs condensation polymers, natural vs synthetic rubber, and basic medicinal chemistry.
How to Use This Book Effectively
The magic of MS Chouhan lies in its massive volume of variations on standard reactions. To get the maximum output, follow this strategy:
- Step 1 (Theory): Do not learn theory from this book. Learn it from NCERT, your coaching notes, or standard textbooks. Use this book strictly for practice.
- Step 2 (Draw Mechanisms): Do not just tick A, B, C, or D in your head. Keep a rough notebook. Draw the reactant, identify the reagent, draw the intermediate, and then draw the final product.
- Step 3 (Analyze Mistakes): If you get a question wrong, figure out why. Did you miss a carbocation rearrangement? Did you forget stereochemistry (inversion vs retention)? Note it down.
- Step 4 (Speed Building): Once your accuracy crosses 80%, start timing yourself to simulate the pressure of NEET or JEE Main.
Frequently Asked Questions
The book is authored by M.S. Chouhan, one of the most highly reputed organic chemistry faculty members in India.
It is published by Shri Balaji Publications, famous for its high-quality science preparation material.
The “Elementary” version is tailored for NEET and JEE Main, featuring standard MCQs. The “Advanced” version is much tougher, featuring multiple-correct, matrix-match, and paragraph questions specifically for JEE Advanced.
Yes, absolutely. It is considered one of the best books for NEET aspirants to solidify their reaction mechanisms and speed.
Yes. The difficulty level of the questions perfectly matches the modern, highly competitive standards of JEE Main.
No, this is strictly a problem-solving book. You must rely on NCERT or class notes for your theoretical foundation.
The book provides answer keys for all chapters. Detailed step-by-step solution manuals are often sold separately or provided at the back depending on the specific edition.
General Organic Chemistry (GOC) and Isomerism are the most critical, as they form the backbone for every reaction mechanism that follows.
Never. NCERT is the absolute bible for Organic Chemistry theory, especially for Biomolecules and Polymers. Use MS Chouhan strictly for practicing MCQs.
Always draw the mechanism on paper. Identify the reagent’s role, watch out for stereochemistry, and always check for possible carbocation rearrangements before forming the final product.
