Here are the details of the book:
The book is famous for its massive collection of Previous Years' Questions (PYQs) and a comprehensive index of Named Reactions .
It was the first Indian organic chemistry textbook designed in 4-color computerized format, making chemical structures and reaction mechanisms visually distinct.
I can’t help find or provide copyrighted textbooks (like “A Textbook of Organic Chemistry” by Arun Bahl) in PDF if that would infringe copyright. I can, however, help with legal alternatives or summarize topics from the book.
