HClO4 is the strongest acid amongst all because the oxidation state or Cl is maximum (+7).

Acidic character increases with increase in oxidation number of central atom...in the given options,HClO4 has +7 oxidation state, which implies it is the strongest acid....In case if two acids have Same Oxidation state of central atom, just count the number of oxygen atoms linked to it, and again it's directly proportional to its acidic strength

Which is the strongest acid in the following : [NEET 2013]a)HClO3b)HCl...
Explanation:
-
- In this case, we need to compare the strength of the conjugate bases of the given acids: ClO3-, ClO4-, SO3^2-, and SO4^2-.
Conjugate bases of the given acids:
a) HClO3 -> ClO3-
b) HClO4 -> ClO4-
c) H2SO3 -> SO3^2-
d) H2SO4 -> SO4^2-
- To determine the strength of these conjugate bases, we need to consider the stability of the negative charge on the oxygen atoms.
- The stability of a negative charge on an oxygen atom is influenced by two factors:
1. Electronegativity of the atom: The more electronegative the atom, the more stable the negative charge.
2. Resonance: The presence of resonance structures stabilizes the negative charge.
Comparison of the conjugate bases:
a) ClO3-: The electronegativity of chlorine is moderate, and there are resonance structures present, which stabilize the negative charge.
b) ClO4-: The electronegativity of chlorine is similar to ClO3-, but ClO4- has more oxygen atoms, which increases the stability of the negative charge.
c) SO3^2-: The electronegativity of sulfur is lower than chlorine, and there are no resonance structures present, reducing the stability of the negative charge.
d) SO4^2-: The electronegativity of sulfur is similar to SO3^2-, but SO4^2- has more oxygen atoms, which increases the stability of the negative charge.
Conclusion:
- Comparing the stability of the conjugate bases, we can conclude that ClO4- (conjugate base of HClO4) is the most stable, making HClO4 the strongest acid among the given options.
