Question:

In the series of group 5A hydrides, of general formula MH3, the measured bond distances are P - H, 1.419 Ã…; As - H, 1.519 Ã…; , 1.707 Ã….
(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.
