Chemistry

This chapter discusses the earlier attempts to classify the elements and concept of periodicity. It explains valency and trends associated with it. It also describes the periodic properties and their variations.

This unit unfolds the concept of chemical bonds and their types. It highlights the electrovalent bond and compounds. It describes the difference between ionic and covalent compounds. The idea of polarity in the covalent bond is also discussed here.

This chapter will shed light on acids, bases and salts. The students will learn to distinguish between acids and bases and also their chemical properties. How acids react with metal and non??etal to produce salt is also explained here.

This chapter discusses the concepts related to analytical chemistry. We will learn about sodium and ammonium hydroxide and their mechanism of action on metallic salt solutions. It also highlights the amphoteric nature of metals, metal oxides and hydroxides.

This chapter sheds light on Gay-Lussac's and Avogadro's law. It explains the mole concept and atomicity. We will learn how to find the percentage composition of an element in a compound and how to determine the empirical formula from percentage composition.

This unit explains the process of electrolysis. We will learn about conductors, insulator and metallic conductors. Moreover, it explains the process of electroplating, electrorefining and electrometallurgy.

This chapter explains the classification of elements into metals and non-metals. It discusses the position of metals and non-metals in the periodic table.The steps involved in the extraction of metals and aluminium are also discussed.

This chapter discusses the structure, properties and preparation of hydrogen chloride gas, hydrochloric acid and ammonia. It also briefs on the preparation, uses and properties of nitric and sulphuric acid.

This chapter sheds light on organic and inorganic compounds and the differences between them. It explains the versatile nature and structural formula of carbon. It also briefs on homologous series, isomerism and nomenclature of compounds.

This unit introduces students to hydrocarbons. Here, they will understand the method of preparation and properties of alkanes, alkenes, alkynes, and acetylenes. It also discusses aromatic hydrocarbons and the properties of benzene.

This chapter talks about the classification, nomenclature, isomerism,?general methods of preparation, physical and chemical properties of alcohols. It also discusses the distinction between primary, secondary, and tertiary alcohols.

This chapter provides knowledge of carboxylic acids and their classification. We will learn the formula, properties, uses and structure of acetic acid. It also discusses some tests used to detect the presence of acetic acid.
