Solved: The As—As bond length in elemental arsenic is 2.48
Chapter , Problem 85AE(choose chapter or problem)
The \(\mathrm{As}-\mathrm{As}\) bond length in elemental arsenic is \(2.48 \AA\). The \(\mathrm{Cl}-\mathrm{Cl}\) bond length in \(\mathrm{Cl}_{2} \text { is } 1.99 \AA\).
(a) Based on these data, what is the predicted \(\mathrm{As}-\mathrm{Cl}\) bond length in arsenic trichloride, \(\mathrm{AsCl}_{3}\), in which each of the three \(\mathrm{Cl}\) atoms is bonded to the As atom?
(b) What bond length is predicted for \(\mathrm{AsCl}_{3}\), using the atomic radii in Figure 7.7?
