Phosphine is a colorless toxic gas. It is a hydride of phosphorus. The chemical formula of this compound is PH3. On the other hand, Silane is also a colorless, pyrophoric, toxic gas with a sharp, repulsive smell. It is also a hydride of silicone. The chemical formula of this compound is SiH4. According to the VSEPR model, provide comments, on the arrangement of electron pairs around PH3 and SIH4. Select one: O a. In each case, the numbers of electron pairs around the central atom are same, therefore same electron pairs arrangement around the central atom. O b. In each case there are a different number of atoms around the central atom, therefore different electron pairs arrangement around the central atom. O c. Since both phosphorus and silicone are in the second period, and making hydride, therefore same electron pairs arrangement around the central atom. O d. Electron pairs arrangement around the central atom (different or the same), depending on the conditions leading to maximum repulsion and we don't have that information therefore can not comments. O e. In each case there are a different number of electron pairs around the central atom, therefore different electron pairs arrangement around the central atom.
