- Aldehydes, Ketones, and Carboxylic Acids
- Amines
- Biomolecules
- Polymers
- Chemistry in Everyday Life

Now, let's discuss which of these chapters are generally considered tough and which ones are easier.

Toughest Chapters in CBSE Class 12 Chemistry

The p-Block Elements
- Why It's Tough: The p-Block elements cover groups 13 to 18 of the periodic table. This chapter is considered tough because it is vast and requires memorization of various properties, reactions, and trends. The chapter includes a lot of exceptions to general rules, making it even more challenging to remember.
- How to Tackle It: Focus on understanding the periodic trends and properties of the elements rather than rote memorization. Make concise notes and use mnemonic devices to remember the trends and exceptions. Practice reaction mechanisms and solve previous years’ question papers to get a better grasp of the content.
Coordination Compounds
- Why It's Tough: This chapter introduces complex concepts like coordination chemistry, which involves understanding the geometry, bonding, and isomerism of coordination compounds. The nomenclature and formation of these compounds can be tricky for many students.
- How to Tackle It: Begin by mastering the basics of nomenclature and bonding in coordination compounds. Use visual aids like models or diagrams to understand the geometry of these compounds. Practice is key, so solve as many problems as you can, especially those related to isomerism and bonding theories.
Chemical Kinetics
- Why It's Tough: Chemical Kinetics involves understanding the rate of chemical reactions and the factors affecting them. The mathematical aspect, particularly the derivation of rate equations and the calculation of half-life, can be daunting for students.
- How to Tackle It: Focus on understanding the basic concepts and the derivation of rate laws. Practice solving numerical problems regularly to get comfortable with the mathematical part. Understanding the graphical representation of reactions is also crucial.
Electrochemistry
- Why It's Tough: Electrochemistry involves concepts related to electrochemical cells, electrode potential, and the Nernst equation. The chapter also includes numericals that require a strong grasp of concepts and calculations, making it one of the tougher chapters in Physical Chemistry.
- How to Tackle It: Start by thoroughly understanding the fundamental concepts such as redox reactions and electrochemical cells. Focus on the derivation of equations like the Nernst equation and practice numerical problems. Diagrams and flowcharts can help in understanding the working of electrochemical cells.
Aldehydes, Ketones, and Carboxylic Acids
- Why It's Tough: This Organic Chemistry chapter is considered tough due to the complexity of reaction mechanisms involved in the formation and reactions of aldehydes, ketones, and carboxylic acids. There are numerous named reactions and their mechanisms that students need to remember.
- How to Tackle It: Focus on understanding the mechanisms of key reactions rather than just memorizing them. Use flowcharts to track the steps in each mechanism and practice by writing out the reactions multiple times. Solving previous year’s questions can also help in mastering this chapter.
