GENERAL CHEMISTRY Std. XI (Part I)

About LIVE Paathshala:

LIVE Paathshala is venture of  Catalyst Academy of Chemistry (professionally managed multi-disciplinary research-based Institute). Since 2014 venture is delivering  Chemistry for students of Grade XI, XII and above through Real-Time LIVE  Interactive Streaming Technology. The Chemistry delivered by us  covers all Basic Fundamentals of Chemistry  including Concepts and its mode of  Applications such as  (How & When), and  its techniques to understand it at all levels of an integrated syllabus of all Boards (C.B.S.E., ICSE, STATE . . . . . .) & Universities . It also guide students about exam  techniques, How to do well in all examination related studies to achieve their Goal.

This  comprehensive course includes Tips, Tricks, Techniques, Practice problems and Applications to keep students away from Chemistry Phobia. It also guide students for selection of Carrier & also make them do well in all aspects.

COURSE OBJECTIVE :
Providing thorough grasp knowledge of Fundamentals, Concepts and its Applications, Create ability to  understand  applied conditions, resolve related issues/difficulties to get result oriented solutions and also to generate interest to know chemistry around us.

DESCRIPTION :
This program is for  students of  Std. XI (all Boards/Curriculum) who are ready for Board/ Entrance Examination. It is intended to be a condensed review of various concepts from a typical Chemistry course.  This course is a blend of video-based instruction and LIVE session interaction. This is the perfect way for students to fulfill their Dreams & to achieve their GOAL.

Main TOPICS:

1. Some Basic Concepts of Chemistry

Laws of chemical combination ; Atomic and isotopic masses; Chemical equivalents; Volumetric calculations in terms of normality. C = 12.00 should be taken as a standard for expressing atomic masses. Relative molecular mass and mole.  Chemical reaction - Stoichiometric calculations based on mass-mass, mass-volume and volume-volume relationships.

2. Atomic Structure

Electrons, Protons and Neutrons as fundamental particles, their charges and masses ; Rutherford’s nuclear model based on the scattering experiment ; Bohr’s atomic model ; Atomic structure: wave mechanical model- a simple mathematical treatment. Quantum numbers; shape, size and orientation of s, p and d orbitals only (No derivation). Hund’s rule of maximum multiplicity. Pauli’s exclusion principle, Aufbau principle, electronic configuration of elements in terms of s, p, d, f subshells.

3. Periodic Table

Atomic number (Proton number) as the basis for classification of the elements in the Periodic Table. IUPAC nomenclature for elements with Z > 100; Extra nuclear structure as the basis of periodicity. Some idea of the following: ionisation enthalpy, electron gain enthalpy, atomic radius, atomic volume, electronegativity, etc must be given. The periodicity of electronic structure leading to the periodicity of elements e.g. the relative ease of ionisation of elements ; Periodicity of elements with reference to s, p, d and f block elements.

4. Chemical Bonding

Kossel-Lewis approach to Chemical Bonding.

Electrovalent Bond ; Electrovalent or ionic bond e.g formation of NaCl, Li2O, MgO, CaO, MgF2, and Na2S ; Factors influencing the formation of ionic bond, e.g electron gain enthalpy, ionisation enthalpy, lattice energy and electronegativity ; The relation between the ionic bonding and Periodic Table ; Variable electrovalency and its causes.

Covalent Bond ; Covalent bond, sigma and pi bonds e.g. formation of ammonia, nitrogen, ethene, ethyne, and carbon dioxide. Resonance ; Variable valency: chlorine exhibits the valency of 1,3,5 & 7 ; Deviation from Octet rule and Fajan’s rules.

Co-ordinate or dative covalent bond: e.g. formation of oxy-acids of chlorine.

Hydrogen bonding: its essential requirements, the examples of hydrogen fluoride, water (ice), alcohol, etc may be considered.

Metallic bonding: van der Waals’ forces.

Valence Shell Electron Pair Repulsion Theory: Hybridization and shapes of molecules: hybridization involving s, p and d orbitals only; sigma and pi bonds.

Molecular orbital theory: Qualitative treatment of homonuclear diatomic molecules of first two periods (Hydrogen to Neon). Energy level diagrams, bonding, antibonding molecular orbitals, bond order, paramagnetism of O2 molecule.

5. The Gaseous State

The gas laws, kinetic theory treated qualitatively; PV = nRT or PV= (w/M)RT and the application of this equation of state; Non ideal behaviour of gases and van der Waals’ equation ; Dalton’s law, the Avogadro’s constant, the mole, Graham’s law of diffusion, simple numerical problems on the above.

6. Surface Chemistry

Adsorption; Colloidal State: Preparation and properties of colloids, both lyophilic and lyophobic colloids. Precipitation as evidence that the colloidal particles are charged. Idea of gold number is required, but application of gold number is not required. The importance of large surface area in adsorption should also be appreciated; Chromatography

7. Chemical Kinetics

Rate of a chemical reaction, basic idea of order and molecularity of a reaction.

8. Chemical Energetics

Introduction ; First law of Thermodynamics and its mathematical statement; Ideas about Heat, Work and Energy; Second law of thermodynamics - Reversible and irreversible changes, isobaric, isochoric adiabatic processes; Entropy, Free Energy. Spontaneity of a chemical change. ?G° = -2.303 RT logKeq; Third Law of Thermodynamics - statement only; Thermochemistry: Definitions; Constancy in the heat of neutralisation; Calorific value of a fuel; Hess’s law of constant heat summation - simple problems based on the above definitions and concepts.
