ORGANIC CHEMISTRY provides a basic input of the fundamentals of organic chemistry. It is primarily meant for undergraduate students having chemistry as one of the major subject enrolled in B.Sc courses such as B.Sc (H) chemistry, B.Sc Life Sciences, B.Sc (Physical Sciences) and many more. Organic Chemistry is composed of huge number of molecules whose role is best described by their formulas and structures comprising of atoms, bonds, electrons, charges etc. Thus the challenge lies how their action is well explained on paper. Hence, an initiation is brought through this book which includes the fundamentals of organic chemistry such as what is organic chemistry, structure and bonding, organic reaction mechanism, stereochemistry, aliphatic hydrocarbons and concept of aromaticity. The core content is presented with the skeleton of proposed mechanisms and solved problems. The book fulfils the requirements of CBCS (Choice based credit system) syllabus followed in different Indian Universities and hence can serve as a text book for students studying in these universities. This book can act as a reference book for students preparing for competitive examination and entrance examinations such as Masters D.U, Masters (Central and State Universities), IIT-JAM, CSIR-JRF, NET, GATE, TIFR, IISc etc as advance knowledge of the essential topics is also encapsulated.
