However, the extent of chlorination is difficult to control: the reaction is not regioselective and often results in a mixture of various isomers with different degrees of chlorination, though this may be permissible if the products are easily separated. More than 2000 compounds have been discovered, which are naturally formed. The chemical symbol for Chromium is Cr. [55] The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. The solutions proved to be far more effective antiseptics than soap (Semmelweis was also aware of their greater efficacy, but not the reason), and this resulted in Semmelweis's celebrated success in stopping the transmission of childbed fever ("puerperal fever") in the maternity wards of Vienna General Hospital in Austria in 1847. The chemical symbol for Thallium is Tl. Under standard conditions, it is the lightest metal and the lightest solid element. Although Scheeles name for chlorine (hypochlorite) remained in wide use until 1809 (when Antoine Lavoisier gave it the present name), other names were used too; notably dephlogisticated marine acid by Joseph Priestley in 1772.
