This section is specifically designed to prepare students for high-frequency, high-accuracy questions on functional groups and nomenclature asked in competitive examinations such as JEE (Main & Advanced), NEET, and other national-level tests. The focus is on speed, precision, and elimination-based reasoning.
In this section, you will practice:
Rapid identification of functional groups in complex structures
IUPAC naming of polyfunctional and highly substituted compounds
Priority rules and functional group hierarchy in tricky questions
Commonly tested exceptions and confusing nomenclature cases
Conversion between structural formulas and IUPAC names
Multiple-choice questions with close options and traps
Assertion–reason, match-the-following, and integer-type problems
NCERT-based and previous-year exam pattern questions
The content is structured to improve exam temperament, strengthen logical elimination techniques, and ensure error-free nomenclature under time pressure.
Master functional groups and nomenclature at the competitive exam level to confidently score in organic chemistry sections and avoid common naming and identification mistakes.
