Write the order of thermal stability of the hydrides of Group 16 elements. Thus HF is most stable while HI is least stable. It describes and explains how the thermal stability of the compounds changes as you go down the Group. This is because down the group, size of the element (M) increases, M-H bond length increases and thus, stability of M-H bond decreases so that it can be broken down easily. The decreasing stability of the hydrogen halide is also reflected in the values of dissociation energy of the H-X bond $\begin{matrix}H-F&H-Cl&H-Br&H-I\\ 135\,kcal\,mol ^{-1}&103\,kcal\,mol ^{-1}&85\,kcal\,mol ^{-1}&71\,kcal\,mol ^{-1}\end{matrix}$ This is due to a decrease in the bond dissociation enthalpy (H-E) of hydrides on moving down the group. So, as the thing goes, Lithium forms oxides(M2O) one oxygen balanced by two lithium atoms. stability is H F > H C l … The correct order of thermal stability of hydroxide is. a) The thermal stability of hydrides decrease on moving down the group this is because of decrease in the bond dissociation enthalpy of hydrides.H2O>H2S>H2Se>H2Te>H2Po b) Reducing character:All hydrides of group 16 elements, except H2O, are reducing agent.The reducing power of these hydrides increase in going from H2S to H2Te, which may be due to increase in the size of the atom and hence … Thermal stability of carbonates increases in a group as we move from top to bottom & decreases in a period as we move from left to right.
