Fromthe exam point of view, classification of elements is very important. Most of the questions in the final exam and various competitive exams appear from this chapter. So learning all the concepts from this chapter is important. From this chapter, students will also learn about the s-block, p-block, d-block and f-block elements from the periodic table, trends in physical and chemical properties and chemical reactivity. By learning this chapter thoroughly, students will obtain good score in the exam.

Valence electrons, ionic bond, covalent bond, bond parameters, Lewis structure, polar character of covalent bond, covalent character of ionic bond, valence bond theory, resonance, geometry of covalent molecules, VSEPR theory, concept of hybridization involving s, p and d orbitals and shapes of some simple molecules, molecular orbital theory of homonuclear diatomic molecules (qualitative idea only), hydrogen bond.

The fact here is that the field of electrochemistry deals with the redox reactions. It is important for the students to learn this chapter in order to score good marks in the final exam. Students will get questions based on the classical idea of redox reaction, redox reactions in terms of electron transfer reactions, oxidation number and electrode processes. Students are recommended to first complete the entire chapter using the NCERT textbook prescribed by the CBSE board.

Hydrogen is the lightest element with one electron and proton. The most abundant element in the entire universe is dihydrogen. Hydrogen is an important element which makes up 80% of the entire mass of the universe. It is very important for the students to know about this element in order to secure good marks in the final exam. Students will also learn about the preparation and properties of dihydrogen and its applications in our daily life. It might be difficult for the students to grasp all these concepts at a stretch, so making use of a perfect study material will help you through it.

Students will learn about the Alkali metals and Alkaline earth metals which are the group 1 and group 2 in the periodic table. Some of the concepts like physical and chemical properties of s-block elements, general characteristics of compounds and about important compounds like calcium. The biological importance of calcium and magnesium is also explained clearly in this chapter. Periodic table and the elements present in them is a hot topic in the exam perspective. For this reason, students are highly recommended to learn all these concepts thoroughly to score well.

Group 1 and Group 2 elements:

General introduction, electronic configuration, occurrence, anomalous properties of the first element of each group, diagonal relationship, trends in the variation of properties (such as ionization enthalpy, atomic and ionic radii), trends in chemical reactivity with oxygen, water, hydrogen and halogens; uses.

Preparation and properties of some important compounds:

Sodium carbonate, sodium chloride, sodium hydroxide and sodium hydrogen carbonate, biological importance of sodium and potassium. CaO, CaCO3, and industrial use of lime and limestone, biological importance of Mg and Ca.

When it comes to exam preparation, both organic and inorganic chemistry plays an important role in attaining good marks. This chapter will introduce you to concepts such as organic compounds, structural representation, classification, nomenclature, isomerism, purification of organic compounds and quantitative analysis. If students are not able to learn these concepts using the NCERT textbook they can download the PDF of solutions which are available online for absolutely free of cost.

General introduction, methods of purification, qualitative and quantitative analysis, classification and IUPAC nomenclature of organic compounds.

Electronic displacements in a covalent bond: inductive effect, electromeric effect, resonance and hyper conjugation.

Homolytic and heterolytic fission of a covalent bond: free radicals, carbocations, carbanions; electrophiles and nucleophiles, types of organic reactions

The scientific study of properties, structure, reactions, composition and synthesis of organic compounds is called organic chemistry. It teaches the students about concepts like alkanes and its preparation from alkyl halides, unsaturated hydrocarbons and carboxylic acids. Students will also learn about the physical and chemical properties of alkanes as per the prescribed CBSE syllabus. As this chapter is important from the exam point of view, students must highly concentrate on all the concepts and memorise it thoroughly to perform well in the exam.

Various concepts which are related to environment like water pollution, atmospheric pollution, soil pollution and its reasons are explained briefly in this chapter. Along with this students will also learn about the use of pesticides to reduce soil pollution and strategies to control pollution like waste disposal. By learning this chapter thoroughly, students will get to know about the pollution occurring in nature by our activities.

The entire syllabus as per CBSE board is divided portions containing all the concepts divided equally. By doing this, the faculty explain the relationship between the various topics which are of higher importance. At the end of each academic year, the CBSE conducts exams in accordance to the syllabus allotted for each year. This mainly aims to provide students the ability to learn the various concepts that are crucial from the exam perspective.

The highly qualified academic tutors design the solutions with the main objective of providing the best educational content to the students across the country. The solutions are very elaborate so that students get all their doubts cleared instantly.
