Chapter 3, Problem 38P
The percent ionic character of the bonds in several interhalogen Molecules (as estimated from their measured dipole moments and bond lengths) are ClF (11%), BrF(15%), BrCl (5.6%), ICl(5.8%), and IBr (10%). Estimate the percent ionic characters for each of these molecules, using the equation in Problem 37, and compare them with the given values.

"Inert" xenon actually forms several compounds, especially with the highly electronegative elements
oxygen and fluorine. The simple fluorides XeF2, XeF4, and XeF, are all formed by direct reaction of the
elements. As you might expect from the size of the xenon atom, the Xe-F bond is not a strong one.
Calculate the Xe-F bond energy in XeF6, given that the heat of formation is -402 kJ/mol.
To explain why AHan for RbCl is different than that for KCI, the student investigates factors that
affect AHoln and finds that ionic radius and lattice enthalpy (which can be defined as the AH
associated with the separation of a solid crystal into gaseous ions) contribute to the process. The
students consults references and collects the data shown in the table below.

Consider hypothetical elements X2 and Y2. Suppose the enthalpy of formation of the compound XY is – 84 kJ/mol, the bond energy for X2 is 105 kJ/mol, and the bond energy for Y2 is 58 kJ/mol.
A)Estimate the XY bond energy, Ed, in units of kJ/mol.
B)If the dissociation of a X-Y molecule were accomplished by the absorption of a single photon whose energy was exactly the quantity required, what would be its wavelength in nm?
C)Would a green-light photon (λgreen=550 nm) be able to break the above X-Y bond? Explain.
