Question

H2S is less acidic than H2Te and also it is in gaseous state when compared with H2O.give reasons for these two observations

Answer 1

Hi, please consider the answer given below,

What happens is that, hydrogen telluride,  H₂Te normally has lower bond dissociation enthalpy than hydrogen sulphide, H2S.

Therefore what happens is that lower energy is required to break the bonds in hydrogen telluride and thus this leads to the releasing of the H+ very easily and hence this implies that the H₂Te is more acidic.
