What is Selenium tetrafluoride?
'''Selenium tetrafluoride''', also known as '''selenous fluoride''' and '''selenium(IV) fluoride''', is a [[chemical compound]]. Its [[chemical formula]] is SeF<sub>4</sub>. It contains [[selenium]] in its +4 [[oxidation state]]. It also contains [[fluoride]] [[ion]]s. ==Properties== It is a colorless [[liquid]]. It hydrolyses in water giving [[hydrofluoric acid]] and [[selenous acid]]. It is used to add fluoride to other chemical compounds. ==Preparation== It is made by reacting selenium with a little [[fluorine]]. A lot of fluorine makes [[selenium hexafluoride]]. It can also be made by reacting [[sulfur tetrafluoride]] with [[selenium dioxide]]. ==Uses== It is used to make [[wikt:adduct|adducts]] and fluorinating organic compounds. ==Related pages== *[[Selenium tetrachloride]] [[Category:Selenium compounds]] [[Category:Fluorine compounds]]
