What is the contribution of Friedrich Wohler to the development of chemistry?
Wöhler, Friedrich (1800–82) German chemist who first isolated aluminium and beryllium, and discovered calcium carbide. In 1828, his synthesis of urea (from ammonium cyanate) was the first synthesis of an organic chemical compound from an inorganic one; it contributed to the foundation of modern organic chemistry.
What did Wohler produce accidentally in 1828?
Wöhler announced his second discovery in a letter of February 1828 to his Swedish mentor, telling Berzelius that he had discovered how to make urea in the laboratory without the use of a living kidney.
Why is Wohler the father of organic chemistry?
Frederich Wohler was a chemist who isolated pure aluminum. He is considered by many chemists to be the father of organic chemistry because he demonstrated that you could take a nonliving mineral (ammonium cyanate) and make a substance that is present in living beings (urea from urine).
Why Friedrich Wöhler is called the father of organic chemistry?
Why was Wohler experiment so important?
Wöhler demonstrated that organic compounds could be successfully produced from inorganic reactants. His experiment made other chemists optimistic about developing organic substances from inorganic substances.
Who saw benzene in dream?

What was Wohler attempting to create in his experiment which synthesized urea?
In this experiment, Wohler was attempting to make ammonia cyanate, but when the ammonia cyanate formed in these conditions it decomposed and then formed urea.
Who is known as the mother of science?

Who discovered benzene structure?
chemist August Kekulé
German chemist August Kekulé visualized the ring structure of benzene in 1865. Most organic chemical compounds contain loops of six carbon atoms called benzene rings.
