Unit I: 
s-Block Elements

General properties and comparative study of alkali and alkaline earth metals, diagonal relationship, anamolous behaviour of Li and Be, salient features of hydrides and their classification (ionic, covalent and interstitial), solvation and complexation tendencies (Crown ethers and cryptands).

Unit II: 
Periodicity in Properties of p-Block Elements
Pre requisite: General Properties of main group elements mentioned in semester II

Periodicity in properties of p-block elements with special reference to atomic and ionic radii, ionization energies, electron-affinity, electronegativity, allotropy, inert pair effect, catenation including diagonal relationship.

Some important compounds of p-block elements: group 13 elements – boron hydrides (diborane) and borazine; group 14 elements – carbides and its classification, silicates (classification and structural aspect); group 15 elements – structural aspects of oxides and oxy acids of N & P; group 16 elements – structural aspects of oxy acids of S including peroxo acids.

Unit IV: 
Oxidation and Reduction

Reduction potentials – redox half reactions, concept of over potential; diagrammatic presentation of potential data (Latimer, Frost and Pourbaix diagrams); redox stability in water, reactions with water, disproportionation, oxidation by atmospheric oxygen; elements extracted by reduction – Ellingham diagrams.

Unit V: 
Basic Principles of Volumetric Analysis

Pre requisite: Basic principles of acid base titrations.

Simple theoretical background of following types of titrations:

Iodometric & iodimetric titrations: Basic principle, application in standardization of iodine  by CuSO4-hypo and H3 AsO3.

Redox titrations : Standard potential, SHE, electrochemical series, emf calculations, internal & external indicators, applications in K2Cr2O7   oxidation reaction.

Complexometric titrations: Types of EDTA titrations, masking and de-masking agents, metal ion indicator, application in estimation of total hardness.

             Precipitation titrations: Basic principle, application in Volhard’s method.
