Why catenation property is most remarkable in the case of carbon?
The main reason alkali metal dihalides (MX₂) do notformis the high IE₂ of the metal. (a) Why is IE₂ so high for alkalimetals? (b) The IE2for Cs is 2255 kJ/mol, low enough for CsF₂to form exothermically (ΔHf=-125 kJ/mol). This compoundcannot be synthesized, however, because CsF forms with a muchgreater release of heat (ΔHf=-530 kJ/mol). Thus, the break-down of CsF₂ to CsF happens readily. Write the equation for thisbreakdown, and calculate the heat of reaction per mole of CsF.
