Explain the reducing character of 16th group.

Text Solution

Verified by Experts

All the hydrides of group 16 elements are good reducing agents except `H_2O `.
The reducing power of these hydrides increase in going from `H_2S` to `H_2 Te`. It is because of decrease in thermal stability of these hydroxides as we go down the group.
`H_2 O lt H_2 S lt H_2 Se lt H_2 Te lt H_2 Po`
