Q. The correct order of decreasing thermal stability of the hydrides of group 16 elements is

The p-Block Elements - Part2

Solution:

As the size of the element increases down the group, the $E- H$ bond dissociation energy decreases and hence $E- H$ bond breaks more easily. Thus, the thermal stability of the hydrides of group 16 elements decreases down the group, i.e., $H _{2} O > H _{2} S > H _{2} Se > H _{2} Te > H _{2} Po .$
