Class 11–12 Chemistry Key Concepts (CBSE) — JEE/NEET Foundation

Physical, inorganic and organic chemistry from the NCERT syllabus with solved numericals and reaction maps

Ghosla Academy · School Academics Team

This course covers the key ideas of the current NCERT Class 11 and Class 12 Chemistry syllabus in one structured path: mole concept and atomic structure, bonding, thermodynamics and equilibrium, solutions, electrochemistry and kinetics, the d-block and coordination compounds, and organic chemistry from basic principles to amines and biomolecules. Each lesson pairs a clear concept explanation with worked numericals or reaction examples and the mistakes students commonly make. It is designed as a board-plus-foundation course: concepts are explained to NCERT depth with a few extra problem-solving shortcuts that help in JEE Main and NEET. Entrance syllabi and patterns are set by NTA and can change, so always check jeemain.nta.nic.in, neet.nta.nic.in and cbseacademic.nic.in before planning. No course can guarantee a rank or selection; consistent practice is what moves your score.

What you will be able to do

  • Solve mole concept, concentration and stoichiometry problems without unit errors
  • Use quantum numbers, periodic trends, VSEPR and MO theory to predict structure and properties
  • Apply thermodynamics, equilibrium and pH relations to board and entrance-style numericals
  • Work with Raoult’s law, colligative properties, the Nernst equation and rate laws
  • Name coordination compounds and explain d-block properties using simple theory
  • Predict organic reaction products and choose correct tests to distinguish compounds

What you build

  • Physical chemistry formula sheet and 20-numerical practice set
  • Organic reaction map with named reactions and distinguishing tests

What you need to start

  • Current NCERT Chemistry textbooks for Class 11 and Class 12 (rationalised edition)
  • Comfort with Class 10 science and basic algebra and logarithms
  • Notebook and a scientific calculator
