Among the following which one is more acidic ? Give reason. H_(2)O,H_ – InterviewSolution

1.	Among the following which one is more acidic ? Give reason. H_(2)O,H_(2)S,H_(2)Se and H_(2)Te
Answer» SOLUTION :`H_(2)Te` is more acidic, because the SIZE of the central atom INCREASES. The bond (H—Te) dissociation ENTHALPY in`H_(2)Te` is low, therefore the `H^(+)`ion is easily LOST.
