ISC Class 11 Chemistry Syllabus Paper 1 Marks Distribution (Theory)

In the paper, there will be no overall choice. All questions must be answered by students. The internal choice will consist of two questions worth two points each, two questions worth three points each, and all three questions worth five points each. 

ISC Syllabus for Class 11 Chemistry

1. Some Fundamental Chemistry Concepts

• Introduction in general: Chemistry's significance and scope

2. Structure of an Atom

Bohr's atomic model and its limitations (de Broglie's equation, Heisenberg's uncertainty principle), shells, subshells, and orbitals Quantum numbers, s, p, and d orbital shapes The Aufbau principle, Pauli's exclusion principle, and Hund's rule of maximum multiplicity are all rules for filling electrons in orbitals. Atomic electronic configuration, stability of half-filled and filled orbitals

3. Classification of Elements and Periodicity in Properties

Modern Periodic Law and the current form of the periodic table lead to periodic trends in element properties such as atomic radii, ionic radii, valency, ionization enthalpy, electron gain enthalpy, and electronegativity. Elements with an atomic number greater than 100 are classified as having a higher atomic number.

Theory of molecular orbitals in homonuclear diatomic molecules (qualitative idea only). Resonance and the hydrogen bond.

5. States of Matter: Gases and Liquids

To establish the concept of the molecule, states of matter and their characteristic properties are used. Boyle's law, Charles' law, Gay Lussac's law, Avogadro's law, Avogadro's number, ideal gas behavior, and derivation of the ideal gas equation The Kinetic Theory of Gases Van der Waal's equation, liquefaction of gases, and critical temperature are all examples of deviations from ideal behavior.
