This book entitled "General Organic Chemistry Illustrated by Corrected Exercises" is intended for undergraduate students (SMC, SMP and SVT). It will also be useful for students in medicine, pharmacy and all those who are involved in organic chemistry. It is a document that includes two parts, the first one on the basics of General Organic Chemistry and the second one on about four score corrected exercises. Concerning the first part, it is composed of six chapters.- Structure of organic compounds,- Determination of the gross and structural formula of an organic compound,- Nomenclature in Organic Chemistry,- Stereochemistry in Organic Chemistry,- Electronic effects in organic chemistry,- Introduction to reactivity in organic chemistry.The second part gathers about eighty corrected exercises, extracted from the exams of about twenty years (from 1990 to 2012) at the Faculty of Sciences Semlalia of the Cadi Ayyad University in Marrakech, Morocco. Always in order to help the student to understand the General Organic Chemistry and to show him how to treat an exercise of this chemistry.
