A) \[{{H}_{2}}S{{O}_{4}}\]
B) \[HCl{{O}_{3}}\]
C) \[HCl{{O}_{4}}\]
D) \[{{H}_{2}}S{{O}_{3}}\]
Correct Answer: C
Solution :
| The strength of oxyacids can also be decided with the help of the oxidation number central atom. |
| Higher the oxidation number of central atom, more acidic is the oxyacid. \[{{H}_{2}}\overset{+\,6}{\mathop{S}}\,{{O}_{4}},HC\overset{+}{\mathop{l}}\,{{\overset{5}{\mathop{O}}\,}_{3}},H\overset{+}{\mathop{Cl}}\,{{\overset{7}{\mathop{O}}\,}_{4,}}{{H}_{2}}\overset{+}{\mathop{S}}\,{{\overset{4}{\mathop{O}}\,}_{3}}\] |
