S.Y.B.Sc. | Sem IV | CH-401
Physical and Inorganic Chemistry

We are very glad to present this book on “Physical and Inorganic Chemistry’’ of semester – II in the hands of S.Y.B.Sc. students. The book is strictly written according to the semester pattern syllabus framed by the board of studies in Chemistry, KBC NMU Jalgaon, for Second year B.Sc to be implemented from June 2019 and is written in very simple language giving exhaustive details. Questions of various types and numericals are included at the end of each chapter. This will help in generating interest and thorough understanding of the subject. We hope, this book will be useful for students and teachers.
