SF6 is known but SCl6 is not. Why? |
|
Answer» Due to small size of fluorine six F– ion can be accomodated around sulphur whereas chloride ion is comparatively larger in size, therefore, there will be interionic repulsion. This is due to the difference in size of flourine and chlorine. Flourine being smaller in size accommodate its six atoms in given space of sulphur while chlorine being bigger in size is not able to accommodate itself due to repulsion between its six atoms. That's why SF6 is known but SCL6 is not known. |
