CBSE 11 Chemistry · U8
Organic Chemistry: Some Basic Principles and Techniques
General introduction, tetravalence of carbon, shapes and representations of organic compounds, classification, nomenclature, isomerism, reaction mechanism basics, purification methods, qualitative analysis and quantitative analysis. Theory weightage: 11 marks.
Test yourself
A focused, distraction-free run through 50 multiple-choice questions. Hints if you need them; your score at the end.
Difficulty guide
The label describes the problem, not your ability.
1/5 - Foundational
Warm-up setup; checks one basic idea.
2/5 - Routine exam skill
Normal syllabus skill; usually one main rule or interpretation.
3/5 - Standard multi-step
Exam-style problem with multiple steps or a common trap.
4/5 - Hard exam skill
High-end exam problem; combines methods carefully.
5/5 - Challenge
Stretch problem beyond normal exam pressure.
