Give reasons for the following: H2Te ...

Give reasons for the following:
`H_2Te ` is more acidic than `H_2S`.

Text Solution

Verified by Experts

As we move down in a group, the bond dissociation energy of E-H bond decreases because of increasing size of the element E. Therefore `H_2Te` has a smaller bond dissociation energy than `H_2S`. Consequently, `H_2Te `is more acidic than `H_2S`.
