Why is H2S less acidic than H2 Te ?...

Why is `H_2S` less acidic than `H_2` Te ?

Text Solution

Verified by Experts

In `H_2Te`, the size of central Te is more than that of S in H2S and therefore, the distance between the central atom and hydrogen, i.e. Te-H is more than that of S-H. As a result of large bond length, the bond dissociation enthalpy of, Te-His less than that of S-H bond and bond cleavage ofTe-H bond is easy. Therefore `H_2Te` is more acidic than `H_2S`.
