Solution
The acidity of hydrides:
The acidity of given hydrides of the oxygen family will be .
Reason:
The acidity of hydrides depends on the bond dissociation enthalpy.
The Bond Dissociation Enthalpy is the measurement of the amount of energy needed during an endothermic reaction to break down a chemical bond and separate it into two distinct atoms, each of which retains one of the first mutual pair's electrons.
The acidity of given hydrides of the oxygen family increases down the group with a decrease in the bond dissociation enthalpy.
