Question

Which one of the following orders correctly represents the
increasing acid strengths of the given acids?
(a) HOClO < HOCl < HOClO₃ < HOClO₂
(b) HOClO₂ < HOClO₃ < HOClO < HOCl
(c) HOClO₃ < HOClO₂ < HOClO < HOCl
(d) HOCl < HOClO < HOClO₂ < HOClO₃

Answer 1

Answer:

option D

HOCI HOCIO. HOCIO2,. HOCIO3

Answer 2

Acidic strengths of acids is - (d) HOCl < HOClO < HOClO₂ < HOClO₃

Acidic character as suggested by name depicts the acidic content of compound. It is calculated by the electronegativity of central atom.

More electronegative the centre atom is, more is acidic character of oxide.

Acidic character of acids given in question will increase with increase in oxidation number of chlorine.

As oxygen atoms increase so does the oxidation number of chlorine and hence acidic character.
