Wohler repeated the experiment several times, and making sure that he can at will transform inorganic compound (ammonium cyanate) in an organic (urea), he reported his discovery Berzelius. Berzelius was a stubborn man who rarely changed his mind under the influence of someone else, but in this case he was forced to admit that they conducted, Berzelius, separation of organic and inorganic compounds was not as clear as he thought. But one should not overestimate the importance of this work Wohler . In itself it is not so important. Strictly speaking, ammonium cyanate is not typical inorganic compound, but even if we assume it as such, the conversion of ammonium isocyanate to urea (as was eventually shown) is simply the result of changing the arrangement of atoms within the molecule. Indeed, because the urea molecule is actually a rebuilt molecule of the same ammonium cyanate.
