Прочитайте текст и выполните к нему organic chemistry organic chemistry is a study of the compounds of carbon. the name “organic” evolved from the theory that any material derived from or produced by any living organism required a “vital force” identified only with life itself. all other compounds were considered to be of mineral origin and were termed “inorganic”. the organic compounds were thought to be utterly complex and impossible of synthesis in the laboratory. today over 400,000 different organic compounds have been isolated or synthesized and characterized. the number of possible compounds is extremely large. organic compounds can form isomers: that is, different compounds containing the same elements in the same proportions but with different structural or spatial arrangement of the atoms. thus a study of organic chemistry would be extremely complex except for the orderly manner of arrangement and comparison of the various possible classes of compounds. the field of organic chemistry is usually broken down into three divisions, namely: aliphatic, aromatic, heterocyclic. к тексту: i. задайте вопрос к каждому абзацу текста ii. укажите предложения, которые не соответствуют содержанию текста a) organic chemistry is a study of the compounds of carbon. b) all other compounds were considered to be of mineral origin and were termed “organic”. c) the number of possible compounds is extremely small. d) the field of organic chemistry is usually broken down into three divisions.
