Question

The set with correct order of acidity is :

Options

A.HClO < HClO2 < HClO3 < HClO4
B.HClO4 < HClO3 < HClO2 < HClO
C.HClO < HClO4 < HClO3 < HClO2
D.HClO4 < HClO2 < HClO3 < HClO

Solution

For the oxoacids of a halogen atom, acidic strength increases with increase in O. N or with increase in the number of O- atom, thus,
+1           +3           +5           +7
HClO < HClO2 < HClO3 < HClO4
