Give reasons for the following: H_2Teis more acidic than H_2S. |
| Answer» Solution :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`. | |
