Question

What was the contribution of chemist Wohler in organic chemistry?

Answer 1

• In 1828, Friedrich Wohler synthesized urea ($N{H}_{2}CON{H}_2$) by heating ammonium cyanate.

$N{H_4}^{+}CN{O}^{-}\stackrel{heat}{\to }N{H}_{2}CON{H}_2$

• This reaction is also called Wohler synthesis and is considered to be the starting point of organic chemistry.
