Before starting preparation for JEE Main 2019 Examination all aspirants should know the domain of their study. For this they should have the latest syllabus. This article brings to you the latest syllabus of Chemistry for JEE Main Examination 2019. In JEE Main there are two papers i.e., Paper – 1 for B. Tech aspirants and Paper 2 for B. Arch aspirants. JEE Main Paper – 1 is of 3 hours having three subjects i.e., Physics, Chemistry and Mathematics. This syllabus is release by the exam conducting body i.e., National Testing Agency (NTA). Students will get the complete information about all the topics of Chemistry. After getting the detailed syllabus, students can plan their study schedule accordingly. Students can prepare well for their examinations if they know the latest syllabus.
Unit 1: Some Basic Concepts in Chemistry:
Matter and its nature, Dalton's atomic theory; Concept of atom, molecule, element and compound; Physical quantities and their measurements 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.
Unit 2: States of Matter:
Classification of matter into solid, liquid and gaseous states.
Gaseous State: Measurable properties of gases; Gas laws - Boyle's law, Charles’ law, Graham's law of diffusion, Avogadro's law, Dalton's law of partial pressure; Concept of Absolute scale of temperature; Ideal gas equation; Kinetic theory of gases (only postulates); Concept of average, root mean square and most probable velocities; Real gases, deviation from Ideal behaviour, compressibility factor and van der Waals equation.
Liquid State: Properties of liquids-vapour pressure, viscosity and surface tension and effect of temperature on them (qualitative treatment only).
Solid State: Classification of solids: molecular, ionic, covalent and metallic solids, amorphous and crystalline solids (elementary idea); Bragg's Law and its applications; Unit cell and lattices, packing in solids (fcc, bcc and hcp lattices), voids, calculations involving unit cell parameters, imperfection in solids; Electrical and magnetic properties.
