CUET Preparation Today
Arrange the following hydrides in increasing order of thermal stability. A. H2O B. H2Se C. H2Po D. H2Te E. H2S |
A < B < C < D < E C < D < B < E < A C < D < E < B < A A < E < B < D < C |
C < D < B < E < A |
The hydride of oxygen has the highest thermal stability among all while that of tellurium has the lowest. It is because the dissociation energy of the bond between the elements(M) and hydrogen(H) decreases down the group with an increase in the size of the atom situated at the centre. \(H_2Po < H_2Te < H_2Se < H_2S < H_2O\) |
