Class 12 Chemistry Study Notes Previous year question papers , sample paper , NCERT Solutions, and all other study material for chemistry subject of class 12th are present here for students and teachers.
Class 12 Chemistry
Higher Secondary is the most crucial stage of school education because specialized discipline-based, content-oriented courses are introduced at this juncture. Students reach this stage after 10 years of general education and opt for Chemistry to pursue their career in basic sciences or professional courses like medicine, engineering, technology and study courses in applied areas of science and technology at the tertiary level.
Class 12 Chemistry consists of the following chapter in the NCERT Text book : The Solid State, Solutions, Electrochemistry, Chemical Kinetics, Surface Chemistry, General Principles and Processes of Isolation of Elements, The p block elements, The d- and f- Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols, Phenols, and Ethers, Aldehydes , Ketones and Carboxylic Acids, Amines, Biomolecules , Polymers , Chemistry in Everyday Life
