There is also a question and answer section that brings up some important concepts and discusses it for the ease of the students.
The chapter explains what biomolecules are and how they interact with each other and constitute the molecular logic of life processes. This section also contains assignments, revision book and revision of chapters with question — answers. They shall also know the physical properties of ethers, phenols and alcohols, the reactions involved in the process of making alcohol from alcohols, Phenols and Ethers, the reaction for the preparation of ethers from alcohols, alkyl halides and sodium alkoxides, and the reactions involved in the preparation of phenols from benzene sulphonic acids, haloarenes, cumene and from diazonium salts. . Sometimes referred to as the core of all sciences as it helps them Physics, Biology and Maths connect with each other. After completing the chapter, students will be able to describe an electrochemical cell and also differentiate between galvanic and electrolytic cells.

Chapter 6 — Isolation of Elements The 6th chapter deals with the study of isolation of elements and includes the study of a lot of concepts. Students will also be able to define the standard potential of the cell and also learn the application of the Nernst equation for calculating the emf of a galvanic cell.
Must see these questions, just after preparing the chapter for exams. The exercise will help students in practising the structures and formulas from aldehydes ketones and carboxylic acids. Since most of the questions asked in the competitive exams are taken directly from the concepts mentioned in these solution modules, therefore, the students must pay great attention to all the above-mentioned solutions for securing a meritorious position in the exam. The questions and answers segment would help students get answers to some important questions that could prove beneficial in the exams. In case, If not working correctly, let me know by commenting.
Chapter 13 — Amines This chapter on Amines teaches students what amines are and how they are obtained. After a brief on the Principles Isolation of Elements, the chapter goes on to discuss topics like the occurrence of metals, concentration of ores, the process of Extraction of Crude Metal from Concentrated Ore, the Electrochemical Principles of Metallurgy, the Thermodynamic Principles of Metallurgy, the process of refining, the process of oxidation and reduction, and the uses of aluminium, Copper, iron, and Zinc. Since most of the concepts covered in the syllabus are theoretical, students must revise them on a regular basis to avoid the forgetting of concepts. However because of its very unpleasant smell, it has now been replaced by better antiseptic. The chapter also explains the three types of chemical reactions - Instantaneous reactions, moderately slow reactions, and slow reactions.

The rate of change of concentration of any of the reactant or product with time at any particular moment of time is known as Rate of reaction. Industries are good means of livelihood which strengthen the national economy.
Bhabha, Heisenberg, Jagdish Chandra Basu, etc. Chapter 5 — Surface Chemistry This chapter on surface chemistry discusses important concepts like adsorption, catalysis, and colloids. All the concepts and solutions have been explained in a really nice and easy manner for a quick understanding of the students. There is a questions and answers section at the end of the chapter to help students master the concept. In this chapter, students shall first learn about electronic configuration, the occurrence and general characteristics of transition elements with special emphasis on the trends in the properties of the first row 3d transition metals, and also the preparation and properties of some important compounds. Thus the n-1 d configuration of the metal and its ion plays important part in giving the observation set of properties to the metal or its ion. The structures and functions of some of these biomolecules are also discussed in the chapter.
