The valence shell electron-pair repulsion (VSEPR) model is used to predict the shapes of molecules and polyatomic ions. VSEPR is based on the idea that the “groups” or “clouds” of electrons surrounding an atom will adopt an arrangement that minimizes the repulsions between them. In this video, we look at examples of molecules in which there are two groups of electrons around the ...

Nov 25, 2013 · SiI4 > SiBr4 > SiCl4 > SiF4 Molar mass of Si halides have following trends : SiF4 , 104 g /mol SiCl4, 170 g / mol SiBr4, 348 g / mol SiI4, 536 g / mol The dramatic increases in boiling points is due to increase in the intermolecular dispersion forces along with increase in molecular weight as we go from SiF4 to SiI4. This is the ...
