Here are the 10 Concept building Questions for competitive Exams (IIT, NEET, OLYMPIAD, KVPY, NET, GATE, JAM) which comes from my book-
24 Test Papers in Organic Chemistry for JEE (Main & Advanced)
Here is the link from where you can get the book
The objective of this book is to provide test papers to students that have an eclectic mix of questions based on all concepts of organic chemistry, while striking a perfect balance between the number and quality of the questions.
While selecting the questions, the following objectives were kept in mind:
1. The difficulty levels should vary
2. The understanding of the subject is tested
3. All concepts are covered
4. The number of questions are large enough to provide meaningful practice to students.
