Class 11 Chemistry — Chapter 8: Organic Chemistry — Basic Principles and Techniques
90 practice questions · 30 Easy · 30 Medium · 30 Hard
Practise Class 11 Chemistry Chapter 8, "Organic Chemistry — Basic Principles and Techniques", with 90 NCERT-aligned multiple-choice questions. The set is split into 30 Easy, 30 Medium and 30 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Organic Chemistry — Basic Principles and Techniques" is one of the chapters where reactions, named concepts, and balanced numerical work really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Organic Chemistry — Basic Principles and Techniques, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Chemistry mastery score. A few sample questions are shown below; sign in free to practise all 90.
Key concepts: Organic Chemistry — Basic Principles and Techniques (Class 11 Chemistry)
This chapter covers the fundamentals of organic chemistry — IUPAC nomenclature, isomerism, electronic effects, and types of reaction intermediates and mechanisms.
- Nomenclature & classification
- IUPAC rules name organic compounds systematically; compounds are grouped by functional groups.
- Isomerism
- Structural isomers (chain, position, functional) and stereoisomers differ in arrangement of atoms.
- Electronic effects
- Inductive, resonance (mesomeric), electromeric and hyperconjugation effects explain reactivity and stability.
- Reaction intermediates
- Carbocations, carbanions and free radicals; carbocation stability is 3° > 2° > 1°.
- Types of reactions & cleavage
- Substitution, addition, elimination; bonds break homolytically (radicals) or heterolytically (ions).
💡 Exam tips for Organic Chemistry — Basic Principles and Techniques
- Carbocation stability order (3° > 2° > 1° > methyl) drives many mechanisms — learn it well.
- Resonance and hyperconjugation stabilise charges/intermediates; use them to predict the major product.
Sample questions
Functional group −OH belongs to:
Hydroxyl → alcohol (-ol).
Butane and iso-butane are:
Different carbon skeletons; same molecular formula.
A free-radical intermediate has:
•CH₃ (methyl radical).
