Chemistry (School & UG)

Download Q&A

The Chemistry (School & UG) category covers the fundamental to advanced concepts of Chemistry, structured to support Class 11–12 students, competitive exam aspirants, and undergraduate learners. The content emphasizes conceptual clarity, problem-solving skills, and strong alignment with NCERT and university syllabi.

In this category, you will study:

  • Physical Chemistry – atomic structure, thermodynamics, chemical kinetics, equilibrium, electrochemistry, and solutions

  • Organic Chemistry – basic principles, reaction mechanisms, hydrocarbons, functional groups, biomolecules, and polymers

  • Inorganic Chemistry – periodic trends, chemical bonding, coordination compounds, metallurgy, and s-, p-, d-, and f-block elements

  • Numerical problem-solving – formula-based calculations, mole concept, and graph-based questions

  • Reaction mechanisms and derivations with step-by-step explanations

  • Comparisons, trends, and exceptions important for exams

  • NCERT-based theory, supported by diagrams, tables, MCQs, assertion–reason questions, numericals, and PYQs

The content is designed to build strong foundations, improve analytical and quantitative skills, and prepare students for school examinations, competitive exams, and undergraduate assessments.

Develop a clear, logical, and application-oriented understanding of Chemistry to excel academically and confidently tackle problem-based and conceptual questions at both school and UG levels.
