After a discussion about the structures of hydrides of group-15 elements, .Neethu wrote the order of bond angles as `NH_3ltPH_3ltAsH_3`. Also arrange the above hydrides in the increasing order of their thermal stability. Justify your answer.

Text Solution

Verified by Experts

Thermal stability order is `AsH_3ltPH_3ltNH_3` The thermal stability is related to the strength of E-H bond(where E=N, Por As).The strength of E-H bond decreases from `NH_3`to `AsH_3`.
