QuarkQuarkQuark2001 Posted May 23, 2004 Share Posted May 23, 2004 FCl or ClF?? HELP ME PLEASE Link to comment Share on other sites More sharing options...
hierarch Posted May 23, 2004 Share Posted May 23, 2004 there exist some dihalogen molecules: XY = F2, Cl2, Br2, BrCl and ClF Link to comment Share on other sites More sharing options...
BoyGenius1 Posted May 23, 2004 Share Posted May 23, 2004 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. Link to comment Share on other sites More sharing options...

YT2095 Posted May 24, 2004 Share Posted May 24, 2004 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 Link to comment Share on other sites More sharing options...

Please help me .!!! Link to comment Share on other sites More sharing options...
QuarkQuarkQuark2001 Posted June 2, 2004 Author Share Posted June 2, 2004 does the look on electronegativity is a correct way? Link to comment Share on other sites More sharing options...
YT2095 Posted June 2, 2004 Share Posted June 2, 2004 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 Link to comment Share on other sites More sharing options...
QuarkQuarkQuark2001 Posted June 2, 2004 Author Share Posted June 2, 2004 Would Anyone kindly tell me? I need this answer .please Link to comment Share on other sites More sharing options...
chemistry Posted June 3, 2004 Share Posted June 3, 2004 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. Link to comment Share on other sites More sharing options...
