Tag: why carbon is having oxidation state +4 only

[SiF6]2- exist but [CF6]2- does not, why?

A nice question both silicon and carbon belong to group 14 and have 4 electrons in the outermost shell. Their general valency is 4 , but silicon and other elements show higher oxidation states also. Only carbon is the element in group 14 elements that do not have vacant d-orbital. All other elements like silicon
