Chemistry forms the building blocks to understanding the living world. We are living because of the millions of chemical changes that occur in our body every second. From the oxidation of glucose to the mechanism guiding respiration, chemical processes occur throughout nature and within us. We are all made of an assortment of elements like carbon, hydrogen, nitrogen, and so on. However, class 11 is a big leap from class 10. Concepts that seemed simple earlier are now dealt with in much greater detail, leaving students confused about what to study and how to go about studying it.
In such a scenario, most students end up doing badly in their class 11 school exams. This is because they tend to get overwhelmed and are unable to formulate a concrete study plan that will equip them with the resources required to complete the syllabus. Unless you have a tried and tested study plan in place and the help of the right teachers, mentors, and seniors to guide you, class 11 can seem quite difficult. This is why we are here to help you by providing you with a list of the easiest and most scoring chapters of class 11 Chemistry. By studying these, you can fetch great marks all while saving some time.
Class 11 Easy And Scoring Chemistry Chapters
There are 14 chapters that make up the entirety of the Class 11 Chemistry syllabus. Basics are explained in great detail first to help students understand what is going to be taught in the upcoming chapters.
Unit I: Some Basic Concepts of Chemistry
Questions are not frequently set from this chapter but it is still important because it helps students mould their fundamentals. Without a proper understanding about the laws of chemical combination along with Dalton’s atomic theory, students will not be able to proceed to further topics. Mathematical problems on atomic and molecular masses, percentage compositions, and stoichiometry are also given at the end of the chapter as part of NCERT exercises.
Unit II: Structure of Atom
In this chapter, students are taught about the various types of models that were hypothesised to explain the structure of an atom. These include Thompson’s model, Rutherford’s model, Bohr’s model, the Heisenberg principle, and so on. Moreover, the photoelectric effect for which Einstein won the Nobel Prize, is also mentioned in brief.
Unit IV: Chemical Bonding and Molecular Structure
This chapter is of extreme importance. Without a thorough understanding of molecular structures, the knowledge of both inorganic and organic chemistry is incomplete. Several theories are put forward to demonstrate the formation of bonds in atoms and molecules that lead to the formation of different compounds. The VSEPR theory is introduced for the first time in the curriculum along with the concept of hybridisation and the molecular orbital theory.
Unit V: States of Matter: Gases and Liquids
The states of matter are dealt with in this chapter. Several laws are put forward. These include Boyle’s law, Charles law, Gay Lussac’s law, and Avogadro’s law. Examples based on these laws are provided and mathematical problems are set from here. However, the chapter is relatively easy to understand and can fetch you marks easily as long as your concepts are clear. Students should also know how to interchange between units as these are the areas where teachers end up deducting marks.
Unit VI: Chemical Thermodynamics
In this chapter of Chemical Thermodynamics, the 3 laws of thermodynamics are discussed. Enthalpy and entropy are important functions that students need to be familiar with. Path functions like work are explained in detail and graphical questions are asked often. These questions can seem tricky if the student does not have enough practice solving questions.
Unit XI: Some p -Block Elements
A general introduction to p – block elements is provided in this chapter, making it the single most high-weightage chapter in the Class 11 Chemistry curriculum. The reason behind the variation in oxidation states of elements is explained with relevant examples. Although P block consists of many groups, only groups 13 and 14 are dealt with in class 11. Students can score full marks in this chapter if they are able to memorise the basic reactions and take note of the exceptions.
Unit XII: Organic Chemistry – Some Basic Principles and Techniques
The importance of organic chemistry cannot be stressed upon enough. It is not only useful now, but also in higher classes. IUPAC nomenclature of organic compounds is taught here. Electronic displacements in bonds involving the inductive effect, electromeric effect, resonance and hyperconjugation are also discussed. Although this chapter might not seem easy when you first read it, it is actually quite scoring.
Unit XIII: Hydrocarbons
This chapter is an extension of Organic Chemistry that was dealt with in the previous chapter. The classification of hydrocarbons is done here on the basis of the number of atoms and bonds present in the compound. These hydrocarbons are generally divided into alkanes, alkenes, alkynes, and some benzylic compounds. Reactions involving the inductive effect, electromeric effect, resonance and hyperconjugation are dealt with in great detail. You have to know the reaction mechanism behind the most important reactions too. In addition to this, the external features and uses of some important hydrocarbons are also taught.
Unit XIV: Environmental Chemistry
We are all aware about the rising need to go green. Given the rate of pollution in the world, if we do not take stringent action immediately, the damage done can be irreversible. Ozone layer depletion, the formation of reducing and photochemical smog, greenhouse effect, global warming, and acid rain are just some of the topics explained here. Environmental chemistry is all about bringing a change by adopting newer strategies and more environment-friendly technology. These are the Class 11 Chemistry chapters that can help students yield more marks in exams by studying strategically. In a short span of time, these are the chapters you should focus on. Chapters like Environmental Chemistry are particularly easy and can be completed in a few hours.
