The bond lengths of the X − H bonds in NH 3 , PH 3 , and SbH 3 are 1.02, 1.42, and 1.71 Å, respectively. Estimate the length of the As − H bond in AsH 3 , the gaseous compound that decomposes on a heated glass surface in Marsh’s test for arsenic. Which of these four hydrides has the weakest X − H bond?

Solution Summary: The author explains that the length of the As-H bond in AsH 3 depends on the nuclear charge of an atom and its size. The bond strength is inversely proportional to the bond length.
