What, Why, Where, When & How of Chemistry CBSE Class 12 (2008 - 14 Solved Papers + Sample Papers) - set of 2 books is altogether a new approach for practicing and revising Physical & Inorganic Chemistry for Class 12 CBSE Board exams. The books are written by India's most popular author in Chemistry, Dr. O.P. Agarwal who is the author of the Bestseller "IIT Guide for Chemistry" and "Organic Chemistry for JEE Main & Advanced (published by Disha Publication)."

The book covers solutions to the Physical, Organic & Inorganic questions that appeared in the 2008 - 2014 solved papers of CBSE Board Delhi, All India and Foreign (including their compartment papers) papers. The book provides a unique and innovative chapterisation and has been divided on the basis of the types of the questions rather than the typical chapter format. The name of the book follows from the answers it provides to the following 5 questions:

What has been asked in the exam?
Why is this question important? Why this question is repeated many-a-times?
How do I answer this question in the best way?
Where (Delhi/AI/Foreign) did this question appeared?
When (year) was this question asked?
The book also provides 3 Sample papers with detailed solutions. The papers have been designed on the latest pattern announced by the CBSE Board. The book will be an eye-opener for all class 12 students who will appear in the CBSE board examination.
