Question

Which of the following hypohalus acid is most acidic?

• A. $HClO$
• B. $HBrO$
• C. $HIO$
• D. All are same acidic

Answer 1

The correct option is A $HClO$

As the electronegativity of $HClO$ is higher than the bromine and Iodine then the bond between the $Cl-O$ is relatively more strong than the bond between $Br-O,I-O$.So the bond between $H-Cl$ is very weak. So the $HClO$ easily donate the proton from it. Hence $HClO$ more acidic than the other.

Hence option A is correct
