Vedclass · Answer

(B) The thermal stability of the hydrides of group $16$ elements depends on the bond dissociation energy of the $E-H$ bond. As the size of the central atom increases down the group $(O Therefore,the thermal stability decreases in the order: $H_2O > H_2S > H_2Se > H_2Te$. Thus,$H_2Te$ has the lowest thermal stability.

Which of the following molecules exhibits the lowest thermal stability?
