A Concise Text-thesis of Organic Chemistry is a handy guide for chemistry students preparing for Advanced Level certificates. The nature of organic chemistry, compared with computational chemistry, is basically the chemistry of carbon. The book focuses on the synthesis of Novel heterocyclic utilizing green methods. The several methods and reagents for synthesizing organic compounds are explained, using Spectrophotometry techniques. Some of selected compounds were comparison theoretical studies using Gaussian 09 which confirm the experimental data. This book is suitable for students of organic chemistry and for those preparing for postgraduate studies. Readers related to Organic chemistry, Green Chemistry, and Physical chemistry can find this guide relevant.
