Consider the following data expect a bef2 molecule to be, Ask an Expert

Academics

Consider the following data: expect a BeF2 molecule to be linear but an SF2 molecule to be angular.
Solubility in Water Melting
(kg/kg H2O, 25oC) Point (oC)
NaF 0.042 988
NaCl 0.357 801
NaBr 1.16 755
Nai 1.84 651

a) Explain the decreasing melting point from NaF to Nai.
b) Explain the increasing solubility in the same order.
c) Cesium fluoride has a melting point of 682oC and a solubility of 3.67 kg/kg H2O at 25oC. Explain the difference between the properties of CsF and NaF.
