FCl or ClF??

 

HELP ME PLEASE

there exist some dihalogen molecules: XY = F2, Cl2, Br2, BrCl and ClF

when naming molecular compounds, the symbols are in order of electronegativity, from least electronegative to the left to more electronegative on the right. Since fluorine is the most electronegative element, it is always on the right.

THANK YOU

and a good general rule of thumb, if you don`t know which is most reactive, look on your periodic table of elements.

read across the list from left to right. what ever element you can see 1`st will be the 1`st in your formula and whicher is last will be the last in your formula.

this is only a General rule though

How about OCl2 or Cl2O?

Please help me .!!!

does the look on electronegativity is a correct way?

it is only a general rule, best used for 2 element compounds, in the case of OCl or ClO3 or 4, that part is then treated as an Ion, and that Ion is the more electro negative and so will apear after the more electro pos IE/

 

NaClO3 not ClO3Na

Would Anyone kindly tell me?

I need this answer .please

ClF, F is more electronegative and possesses the neg. oxidation state. Cl thus would on the positive side. The anion or the negatively charged element is always written last.
