On completion of this course, the students will be able to-

 

CO17: describe the periodicity in properties, structures, applications and chemical reactivity of the s-block and p-block elements.

CO18: interpret and apply Frost and Latimer diagrams to predict chemical behaviour and relative strengths of species as reductants and oxidants.

CO19: compare the properties, structure and bonding of different interhalogen compounds and xenon compounds.

CO20: describe the structural aspects and applications of important inorganic polymers.

CO21: compare various theories of acid and bases and predict the strength of acids and bases.

CO22: classify various types of solvents and differentiate between some non-aqueous solvents based on their properties and label different types of reactions in non-aqueous solvents
