Organic chemistry is the largest area of specialization among the various fields of chemistry. It derives its name from the fact that in the 19th century most of the carbon compounds then known were considered to have originated in living organisms..
Creation of the École Nationale Supérieure de Chimie of Paris by Charles Friedel, holder of the Chair of Organic Chemistry at the Sorbonne, as “a laboratory for practical and industrial chemistry for the Paris Faculty of Sciences”.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and
Comment calculer la composition d’un composé organique ?
L’analyse élémentaire d’un composé organique montre qu’il contient 84 % de carbone et 16 % d’hydrogène. Choisir, parmi les formules moléculaires suivantes, celle en accord avec cette composition. D’après l’analyse élémentaire le composé n’est constitué que de carbone et d’hydrogène. En effet, la somme des pourcentages indiqués totalise 100 %.
Comment représenter une molécule organique ?
Les molécules organiques peuvent être représentées de différentes manières, plus ou moins détaillées. La simple indication des atomes et de leur nombre constitue la formule brute de la molécule.
Qu'est-ce que la chimie organique ?
En chimie organique, on étudie les réactions que les chimistes utilisent pour synthétiser d'incroyables édifices à base de carbone, ainsi que les méthodes d’analyse pour les caractériser. On verra également de quelle manière ces réactions se produisent au niveau moléculaire grâce à des mécanismes réactionnels.

Regional rail network serving the French island of Corsica
Chemins de fer de la Corse (CFC) is the name of the regional rail network serving the French island of Corsica. It is centred on the town of Ponte Leccia, from which three main lines radiate to Ajaccio, Bastia, and Calvi. The section following the northwest coastline between L'Île-Rousse and Calvi, known as the Balagne line, gives access to many beaches and is very popular with tourists.

Heritage railway in France
The Chemin de Fer de la Baie de Somme, is a preserved railway in northern France. The railway is managed by a non-profit organization, which runs from March to December between the towns of the Baie de Somme area: Le Crotoy and Cayeux-sur-Mer via Noyelles-sur-Mer and Saint-Valery-sur-Somme, on metre gauge tracks. The association was founded in 1970 and over the years it has become a major player in tourism development in the Picardy coast and is also responsible for the preservation, safeguarding and enhancement of the fleet full of cars, wagons, steam locomotives and diesel locomotives. The line is one of the closest French heritage lines to the UK, Noyelles is 73 kilometres (45 mi) from Boulogne-sur-Mer and 105 kilometres (65 mi) from Calais. A part of the line has dual gauge track, and although forming part of a group of five lines, at least a part of it has always been open to traffic.
The Chemin de Fer du Blanc-Argent is a nowrap>1,000 mm gauge railway in the region of Centre-Val de Loire, France, part of which is still open to traffic, whilst another section is now operated as a heritage railway.
