About The book
 
The specific book titled "CBSE Quick Revision in 4 Hours in Chemistry for Class 12th" appears to be one of many revision resources designed for students preparing for the CBSE Class 12 Chemistry board exams. While a book with this exact title might not be a widely published, single-author title, the name is indicative of a common category of last-minute, exam-focused study materials.
These types of quick revision resources generally offer:
 * Concise Summaries: They boil down the entire Class 12 Chemistry syllabus (Physical, Inorganic, and Organic Chemistry) into very brief, exam-oriented points and key formulas.
 * High-Weightage Topics: The content is typically focused on topics known to carry significant marks in the board exams, such as:
   * Physical Chemistry: Numerical problems from Solutions, Electrochemistry, and Chemical Kinetics.
   * Inorganic Chemistry: Important properties and reactions, especially of d- and f-Block Elements and Co-ordination Compounds.
   * Organic Chemistry: Name reactions, distinguishing tests, and important reaction mechanisms from chapters like Haloalkanes and Haloarenes, Alcohols, Phenols and Ethers, and Aldehydes, Ketones and Carboxylic Acids.
 * Targeted Practice: They often include Very Short Answer, Short Answer, and Long Answer questions with their solutions, directly aligned with the CBSE pattern, to enable rapid self-assessment.
 Note on "4 Hours"
The "in 4 Hours" part is a marketing strategy to emphasize the book's utility for last-minute revision. It suggests the book provides the absolute essentials to quickly recall the core syllabus concepts just before the exam.
