Q49Short answer
Explain why the stability of oxoacids of chlorine increases in the order given below: HClO < HClO2 < HClO3 < HClO4
Show answer
Oxygen is more electronegative than chlorine, therefore dispersal of – – negative charge present on chlorine increases from ClO to ClO4 ion because number of oxygen atoms attached to chlorine is increasing. Therefore, stability of ions will increase in the order given below : – – – – ClO < ClO2 < ClO3 < ClO4 Thus due to increase in stability of conjugate base, acidic strength of corresponding acid increases in the following order HClO < HClO2 < HClO3 < HClO4
