Question
he following acids have been arranged in the order of decreasing acid strength. Identify the correct order ClOH (I), BrOH (II), IOH (III)
Options
A.I > II > III
B.II > I > III
C.III > II > I
D.I > III > II
Solution
ClOH > BrOH > IOH
I II III
As the electronegativity of halogen atom decreases. The acidic strength of its oxo-acid decreases. The electronegativities of halogen atoms is in the order Cl > Br > I.
I II III
As the electronegativity of halogen atom decreases. The acidic strength of its oxo-acid decreases. The electronegativities of halogen atoms is in the order Cl > Br > I.
