Rationale

Students reach this stage after 10 years of general education and opt for Chemistry to continue their career in basic physics or expert courses like medication, engineering, technology, and other affected areas.

Therefore, there is a need to give learners enough conceptual knowledge in Chemistry, which will make them able to meet the challenges of academic and expert studies after the senior secondary stage. The new and updated curriculum is based on a disciplinary program with rigor and depth taking care that the syllabus is not heavy and at the same time it is similar to the global level.

The knowledge linked to the subject of Chemistry has undergone tremendous changes throughout the past decade. Many new areas like synthetic materials, biomolecules, industrial chemistry are coming in a big way and deserve to be an essential part of the chemistry syllabus at a senior small stage.

At the international level, new formulations and classification of elements and compounds, and units of physical measures floated by accurate bodies like IUPAC and CGPM are of immense importance and need to be included in the refreshed syllabus. The revised syllabus takes care of all these peculiarities. Greater emphasis has been laid on the use of new vocabulary, and formulations, the teaching of basic concepts, application of concepts in chemistry to business/ technology, logical sequencing of units, removal of antiquated content and repetition, etc.

Unit – I: Some Basic Concepts of Chemistry

General Introduction: Meaning and scope of chemistry.

Nature of matter, Dalton’s atomic theory: the concept of elements, particles, laws of a chemical compound, and molecules.

Atomic and molecular masses, mole basis and molar mass, percentage composition, experimental and molecular method, chemical reactions, stoichiometry, and estimates based on stoichiometry.

Unit – II: Structure of Atom

Bohr’s model and its limitations, the concept of shells and subshells, dual world of matter and light, de Broglie’s relation, Heisenberg uncertainty principle, quantum quantities, shapes of s, p and d orbitals, rules for filling particles in orbitals – electronic configuration of atoms, Aufbau principle, Pauli’s separation principle and Hund’s rule, security of half-filled and filled orbitals.

Unit – III: Classification of Elements and Periodicity in Properties

Modern periodic law and the modern form of the periodical table, periodic trends in properties of ingredients -atomic radii, Ionization enthalpy, ionic radii, inert gas radii, electron gain enthalpy, electronegativity, valency. 

Unit – IV: Chemical Bonding and Molecular structure

Valence electrons, ionic bond, bond parameters, polar character of covalent bond, covalent bond, Lewis structure, the covalent character of ionic bond, resonance, geometry of covalent molecules, the concept of hybridization, valence bond theory, VSEPR theory, involving s, p and d orbitals and shapes of some simple molecules, molecular orbital theory of homonuclear diatomic molecules(qualitative purpose only), hydrogen bond.

Unit – V: States of Matter: Gases, Liquids, and Solids

Three states of matter, intermolecular interactions, melting and boiling points, types of bonding, Charles law, Boyle’s law, Gay Lussac’s law, Avogadro’s law, the role of gas laws in the concept of the molecule, ideal behavior, Avogadro’s number, ideal gas equation. Deviation from ideal behavior, critical temperature, liquefaction of gases, kinetic energy, and molecular activities (elementary idea) Liquid State: vapor tension, viscosity and surface tension (qualitative idea only, no math derivations) Solid-state: Classification of solids based on different binding forces: molecular, ionic, covalent and metallic solids, amorphous and crystalline solids. Unit cell in two-dimensional and three-dimensional structures, estimation of the density of unit cell, binding in solids, packing efficiency, voids, number of scraps per unit cell in a cubic unit cell, electrical and magnetic properties.
