This section presents realistic, concept-integrated case studies that demonstrate how functional groups and systematic nomenclature are applied in chemical analysis, synthesis, and real-world problem-solving. It is designed for Class 11–12 students, competitive exam aspirants, and undergraduate learners to bridge theory with practical understanding.
In this section, you will analyze:
Identification of functional groups in complex organic molecules
Stepwise naming of polyfunctional and substituted compounds
Case studies involving drug molecules and industrial chemicals
Structural interpretation based on functional group behavior
Comparison of common names vs. IUPAC names in professional use
Reaction pathway analysis using functional group transformation
Exam-oriented case-based questions following NCERT and competitive patterns
The case studies are structured to enhance analytical thinking, improve structural interpretation skills, and strengthen the ability to apply nomenclature rules in realistic chemical scenarios.
Build confidence in functional group analysis and nomenclature through case studies that mirror exam questions, laboratory situations, and industrial documentation practices.
