Chapter 4, Problem 88AE(choose chapter or problem)
In the series of group 5A hydrides, of general formula MH3, the measured bond distances are P一H, 1.419 Å; AsH, 1.519 Å; Sb
H, 1.707 Å. (a) Compare these values with those estimated by use of the atomic radii in Figure 7.6. (b) Explain the steady increase in M
H bond distance in this series in terms of the electronic configurations of the M atoms.
