Question

Give reason for the following
H2S is less acidic than H2Te​

Answer 1

as S is more reactive also h2s released all h ionnnn

Answer 2

As the atomic size increases down the group , the bond length increases hence the bond strength decreases

Consequently the cleavage of X-H bond (X=O, S, Se, Te, etc.)becomes easier

Thus , H2S is less acidic than H2Te.
