CBSE Class 12 Chemistry Marking Scheme 2024
Physical Chemistry
Solutions: This section talks about solutions, colligative properties, and both ideal and non-ideal solutions.It’s crucial to comprehend concentration units and colligative properties such as freezing point depression, boiling point elevation, osmotic pressure, and unusual behavior of solutions.
Chemical Kinetics: This part delves into the speeds of chemical reactions, the factors influencing reaction rates, and the order of reactions. Make sure to have a solid understanding of rate laws, rate constants, and reaction mechanisms.
Electrochemistry: It includes concepts like conductivity, electrolytic cells, electrolysis, and redox reactions. Give special attention to the Nernst equation, electrolysis processes, and the electrochemical series.
Surface Chemistry: This chapter centers on the adsorption phenomenon, the different types of adsorption, and the factors impacting adsorption. Grasp the ideas behind physisorption and chemisorption, as well as their applications in catalysis.
Inorganic Chemistry
p-Block Elements: It discusses the characteristics and behaviors of elements in Groups 13 to 18. Pay attention to how these elements behave in terms of periodic trends, how they are prepared, and the significant compounds they form.
d-Block Elements: This chapter focuses on the characteristics and behaviors of transition metals. Get a good grasp of concepts like coordination compounds, isomerism, and the different oxidation states these metals can have.
f-Block Elements: Here you will learn about the properties and reactions of lanthanides and actinides. Make sure to understand their electronic configuration, oxidation states, and the practical uses of these elements in various applications.
Organic Chemistry
Aldehydes, Ketones, and Carboxylic Acids: In this section, we’ll explore how to make them, what they’re like, and how they react with aldehydes, ketones, and carboxylic acids. Make sure you understand the reactions where they join with other substances, the processes where they gain or lose oxygen, and tests to identify them.
Biomolecules: This part is all about carbohydrates, proteins, nucleic acids, and fats. Get to know the makeup, characteristics, and functions of these important biomolecules.
Polymers: This chapter focuses on different kinds of polymers, how they behave, and how to create them. Understand the processes of putting together polymers, both by adding molecules and by condensing them, and become familiar with the common types of polymers out there.
