Arrange the following hydrides of group 16 elements in order of increasing stability.

A

`H_(2)S lt H_(2)O lt H_(2) Te gt H_(2)Se`

B

`H_(2)O lt H_(2)Te lt H_(2)Se lt H_(2)S`

C

`H_(2)O lt H_(2)S lt H_(2)Se lt H_(2)Te`

D

`H_(2)Te lt H_(2)Se lt H_(2)S lt H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
D
There is a decrease in bond enthalpy (H - E) as the size of the element increases on moving down the group hence, the stability decreases on moving down the group.
