Question
In the series of group 5A hydrides, of general formula
MH3, the measured bond distances are P¬H, 1.419 Å;
As¬H, 1.519 Å; Sb¬H, 1.707 Å. (a) Compare these values
with those estimated by use of the atomic radii in
Figure 7.7. (b) Explain the steady increase in M¬H bond
distance in this series in terms of the electron configurations
of the M atoms.
