Highlights

The CBSE Syllabus for Class 11 Chemistry contains information on practicals, projects, assignments, and other topics that must be addressed over the academic year. Students can better comprehend the course structure of Chemistry by familiarising themselves with the curriculum. The final exam question paper will be prepared according to the CBSE class 11 Chemistry syllabus.

Chemistry in class 11 is a large subject that requires a thorough comprehension of the principles and themes. Students can better comprehend the course structure of Chemistry for the academic year by familiarising themselves with the CBSE Class 11 Chemistry curriculum. Class 11 students learn what they need to study, how much each unit is worth, and how long it will take them to complete it by going over the syllabus. They may simply design their study schedule based on this information. The final exam question paper will be prepared according to the CBSE Class 11 Chemistry syllabus, thus students must adhere to it. The CBSE Syllabus for Class 11 Chemistry contains information on practicals, projects, assignments, and other topics that must be addressed over the academic year.

Gases and Liquids:

Three states of matter, intermolecular interactions, forms of bonding, melting and boiling temperatures, and the importance of gas laws in explaining the notion of the molecule are all discussed. Boyle's law, Charles law, Gay Lussac's law, Avogadro's law, ideal behavior, empirical derivation of gas equation, Avogadro's number, ideal gas equation, and departure from ideal behavior are all terms used in the field of mathematics.

Chemical Thermodynamics:

System Concepts and Types, Environment, Work, Heat, and Energy, Extensive and Intense Properties, State Functions Internal energy and enthalpy, U and H measurements, Hess's rule of constant heat summation, enthalpy of bond dissociation, combustion, formation, atomization, sublimation, phase change, ionization, solution, and dilution are all covered under the first law of thermodynamics. Thermodynamics' second law (brief introduction)

Chemistry Practical Syllabus for CBSE Class 11 for Term 2

The Chemistry Practical in CBSE Term II is worth 15 points. It will be run under the direction of the topic instructor. This contributes to the subject's total practical grade.
OR
If the lockdown persists through December 2021, the subject instructor will perform a Practical Based Assessment (pen-paper) worth 10 points and a Viva of 5 points after Term II. This would help with the subject's total practical grade.
