Organic Chemistry

Download Q&A

Organic Chemistry deals with the structure, properties, reactions, and synthesis of carbon-containing compounds, forming a core part of school-level chemistry, undergraduate curricula, and competitive examinations. This category is designed for Class 11–12 students, undergraduate learners, and competitive exam aspirants, with strong emphasis on conceptual clarity, reaction mechanisms, and application-based learning.

In this section, you will study:

  • Basic principles of organic chemistry – hybridization, bonding, and structure

  • Classification and nomenclature of organic compounds

  • Isomerism – structural and stereoisomerism

  • Reaction mechanisms – substitution, addition, elimination, and rearrangement

  • Hydrocarbons – alkanes, alkenes, alkynes, and aromatic compounds

  • Functional groups and their chemistry – alcohols, aldehydes, ketones, acids, amines, etc.

  • Named reactions and reagents essential for exams

  • Biomolecules and polymers (introductory to UG level)

  • Spectroscopic methods for structure determination (introductory)

  • NCERT- and UG-aligned explanations, supported by reaction schemes, mechanisms, examples, MCQs, and PYQs

The content is structured to build step-by-step understanding, enhance mechanistic thinking, and help students predict reaction outcomes and solve complex problems.

Master Organic Chemistry to develop strong analytical and reasoning skills, essential for school exams, undergraduate studies, and competitive examinations.
