IIT JEE Main Chemistry Syllabus – JEE Main entrance exam for admission to B.E. / B.Tech. comprises of three subjects – Mathematics, Physics and Chemistry. Candidates should cover the syllabus of class 11 and 12 thoroughly. Here we have compiled a list of topics in Chemistry that form a part of the syllabus of JEE Main Chemistry paper. The topics are as follows-
Some Basic Concepts in Chemistry: Matter and its nature, Dalton’s atomic theory, Concept of atom, molecule, element and compound, Physical quantities and their measurement in Chemistry, precision and accuracy, significant figures, S.I units, dimensional analysis, laws of chemical combination, Atomic and molecular masses mole concept, molar mass, percentage composition, empirical and molecular formulae, chemical equations and stoichiometry.
States of Matter: Classification of matter into solid, liquid and gaseous states.
- Measurable properties of gases: Gas laws- Boyle’s law, Charle’s law, Graham’s law of diffusion, Avogadro’s law, Dalton’s law of partial pressure, concept of hybridization involving s, p and d orbitals; Resonance.
- Molecular Orbital Theory: Its important features, LCAOs, types of molecular orbitals (bonding, antibonding) sigma and pi bonds, molecular orbital electronic configurations of homonuclear diatomic molecules, concept of bond order, bond length and bond energy.
- Elementary idea of metallic bonding. Hydrogen bonding and its applications.
