Like other silicon protecting groups, the silicon unit is easily removed in alkaline or fluoride ion-containing systems. In addition, the phenyl ring in the structure can be converted to a cyclohexyl structure under hydrogenation, while the chlorine atom on silicon is not affected by hydrogenolysis...
example, sodium chloride, more commonly known as table salt, can be expressed by the formula unit NaCl. Regardless of how many ions of sodium chloride are being used in a chemical equation, the formula unit for sodium chloride is the simplified expression of one sodium atom to one chlorine ...
Determining the Formula Unit for a Compound In many cases, all that is required to find the formula unit for an ionic compound, and for some simple crystalline covalent compounds, is knowledge of how many single bonds the elements are able to form. In the case of metals, this is the numb...
