The book entitled “University Chemistry” is a very sincere attempt to arouse the interest of the students in Physical Chemistry-I taking chemistry subject as their Honours paper in B.Sc. course. This book is written in easily understandable and catchy language so that the students can easily grasp the contents that they read. This book is intended as a theory book for students appearing for B.Sc. (Hons.).
The salient features of this book are –
* It is based on the prescribed syllabus for the B.Sc. courses of the state universities.
* It provides basics of theory.
* It gives concise and pointwise information of the subject matter.
* It includes solved problems in each chapter and different questions at the end of each chapter.
