Chemistry is one of the most interesting and challenging subjects in JEE Main preparation. You are tested on your understanding of different concepts through thought-provoking questions. There are several sections in this subject, including Organic Chemistry, Physical Chemistry, and Inorganic Chemistry. The syllabus for JEE Main Chemistry covers a wide range of topics not covered in class 12 Chemistry.

Top 7 Difficult Topics in JEE Main 2023 Chemistry

You need to read this blog if you’re an aspirant for JEE Main. For your convenience, we have compiled a list of the seven most difficult topics in JEE chemistry, from organic chemistry to inorganic chemistry.

• Equivalent Concept

In Physical Chemistry, it is among the most engaging topics. In a chemical reaction, an equivalent is the amount of one element that reacts with an arbitrary amount (typically one mole) of another element. Compared to mole analysis, it is more efficient for stoichiometry calculations. An equivalent is the archaic unit measurement used in Chemistry and Biological sciences. Its concepts are one of the most difficult to understand as many factors play an important role in determining its value.

• Electrochemistry

Electrochemistry is the study of chemical reactions involving electric currents. Electrolysis, electromotive force, and oxidation-reduction reactions are examples of electrochemistry. This subject involves understanding electrical energy and how it can be used for various purposes, such as batteries or fuel cells. It also includes topics on corrosion inhibition. The JEE Chemistry syllabus includes a chapter on electromotive force and electrochemistry. Even though the concepts are difficult, this is an easy topic to score once you master the basics. It is a high scoring section because the questions are mostly application-based.

• Ionic Equilibrium

The state of equilibrium between an ionic compound and its ions is known as ionic equilibrium. When they dissolve or react with water, they produce electrically neutral products. At any given temperature, the ionization constant determines the degree of dissociation (ionization) in aqueous solutions, as well as whether there will be electrical neutrality during dissolution or reaction. Since it’s one of the topics included under JEE mains Chemistry syllabus, it is imperative to understand how to solve these questions easily by understanding key concepts like Ksp value and pH value calculations, etc.

• Inorganic Chemistry

Another important segment in chemistry is Inorganic Chemistry, which is easy to score from a JEE perspective. During inorganic reactions, elements combine to form compounds under different conditions. This subject plays a fundamental role for students preparing for their JEE main exams because a lot of questions based on this topic are asked in JEE owing to the chapter’s importance. 

• Organic Chemistry

Due to its vastness and complexity, Organic Chemistry is one of the most challenging sections of the chemistry syllabus for JEE mains. Molecules are formed when atoms come together in organic reactions. When it comes to explaining organic questions during exams, functional groups are very important. Several concepts within organic chemistry have exceptions and a lot of questions are asked from these parts, making them crucial.

• Gaseous State

Gases do not have a fixed shape or volume. In contrast to solids or liquids, which tend to maintain a constant boundary due to their strong intermolecular forces, they spread to fill the available space, taking on the shape of their container. As one of the most important chapters in the JEE Chemistry syllabus, this topic covers topics such as atmosphere, kinetic molecular theory, gas laws, and ideal gas equations.

• Thermodynamics

Thermodynamics is the study of heat and the relationship between it and other forms of energy. When one wants to answer questions in the JEE Main exam related to this topic, it is important to understand topics such as temperature, internal energy, heat transfer, etc. There are different types of thermodynamic laws, including the Law Of Conservation Of Energy, Zeroth Law, first law, second law, Boyle’s Gas Laws, and Charles’ Gas Laws.

These are some of the difficult topics included in JEE Main Chemistry. It is important that you pay close attention to these topics in order to succeed in this subject. Learn the key concepts and formulas of each topic so that you can easily answer questions on them in exams.

The most important thing is to go through the JEE mains 2021 Chemistry chapter-wise questions to get an idea of what to expect. Moreover, you can get a complete overview of JEE Main 2023 syllabus along with weightage to help you plan your learning. Keeping a good pace at the beginning will prevent you from lagging later due to time constraints.
