NEET 2022 Chemistry Syllabus Class 11
The Physical Chemistry, Inorganic Chemistry, and Organic Chemistry sections from classes 11 and 12 make up the NEET Chemistry Syllabus. Chemical reactions, processes, compositions, and chain reactions are considered to be the bare minimum, essential concepts that students should be familiar with for the NEET Chemistry section. It has frequently been noted that NEET exam questions are frequently constructed entirely from ideas found in NCERT textbooks. Additionally, based on trends from prior years, it appears that students in the Chemistry part are evaluated using questions that are roughly of the same type but vary in complexity.

NEET 2022 Chemistry Syllabus Class 11
Unit I: Some Basic Concepts of Chemistry
This is the general introductory chapter which explains to us the importance and scope of chemistry and introduces to us the laws of chemical combination as well as Dalton’s atomic theory about the concept of elements, atoms and molecules. It also introduces the concepts of atomic and molecular masses, mole concept and molar mass; percentage composition and empirical and molecular formula; chemical reactions, stoichiometry and calculations based on stoichiometry.
Unit II: Structure of Atom
As the chapter suggests, it details the structure of an atom and – Atomic number, isotopes and isobars. Concept of shells and subshells, dual nature of matter and light, de Broglie’s relationship, Heisenberg uncertainty principle, concept of orbital, quantum numbers, shapes of s,p, and d orbitals, rules for filling electrons in orbitals – Aufbau principle, Pauli exclusion principles and Hund’s rule, electronic configuration of atoms, stability of half-filled and completely filled orbitals.
Unit III: Classification of Elements and Periodicity in Properties
Modern periodic law, long-term form of periodic table, periodic trends in elemental properties such as electronegativity, valence, ionisation enthalpy, and atomic and ionic radii
Unit IV: Chemical Bonding and Molecular Structure
Valence electrons, ionic bonds, covalent bonds, bond parameters, Lewis structures, the polar nature of covalent bonds, valence bond theory, resonance, molecular geometry, VSEPR theory, the idea of hybridization involving the s, p, and d orbitals and shapes of some simple molecules, and molecular orbital theory of homonuclear diatomic molecules (qualitative idea only) are all topics explained in this chapter. The hydrogen bond is also explained.
Unit V: States of Matter – Gases and Liquids
This chapter sheds light on the three states of matter, intermolecular interactions, types of bonding, melting and boiling points, the role of gas of elucidating the concept of molecule, Boyle’s law, Charle’s Law, Gay Lussac’s law, Avogadro’s law, ideal behaviour of gases, and empirical derivation of gas equation. Also covered are Avogadro number, ideal gas equation, kinetic energy and molecular speeds (elementary idea), deviation from ideal behaviour, liquefaction of gases, critical temperature.
