The idea of the book entitled “Success Guide to Organic Chemistry Volume 2” was born because of the lack of any comprehensive book covering all the aspects of various entry level chemistry competitive examinations in particular conducted by CSIR, GATE, TIFR State and National Eligibility Test, but not limited to. Advanced theory in Organic chemistry volume 2 book covers important chapters of organic chemistry namely, 1. Protection and Deprotection Chemistry 2. Reagents 3. Name Reactions and Rearrangement Each chapter has detail concepts and many applied conceptual examples for practice. At the end of every topic practice questions are included. The ultimate purpose of organic chemistry volume 2 book is to equip the reader with conceptual knowledge for organic chemistry and applied aspect with respect to examinations. It contains predigested information on the entire academic subject of organic chemistry for good understanding, assimilation, self-evaluation, and reproducibility. Although I have made every effort to make the book error free, we are under no illusion. I welcome comments, criticism and suggestions from the readers to evolve the contents.
