HOCl vs HOI

[Zenita Leang 2K]

Why is HOCl a stronger acid than HOI?

[405169322]

yes, because HOCl is more stable. Mainly because the O–H bond in HOI is stronger than the O–H bond in HOCl. Making HOCl more likely to donate a proton.

[Andrew Bennecke]

HOCl is a stronger acid than HOI because the Cl is far more electronegative than the I in their respective acids. The more electronegative a molecule is, the less electron density around the H, making it easier for the H to be donated to another molecule. The easier a H atom is donated from an acid, the stronger that acid is, so since HOCl is more electronegative, it can lose the H atom easier and is therefore a stronger acid than HOI.

Cl is more electronegative than I. The O-H bond in HOI is stronger than the O-H bond in HOCl. As a result, HOI is a weaker acid.

Cl is more electronegative, making the electron density around the H atom less. Therefore, it can more easily be donated.

HOCl is stronger because Cl is more electronegative, pulling the electrons close towards it. This weakens the O-H bond, making it easier to lose a proton(H+).

Electronegativity is the tendency of an atom to attract a bonding pair of electrons and Cl is more electronegative than I. The weaker the bond the more likely it will lose an H+. Also HOCL is more stable.

[Ahmed Mahmood 4D]

HOCl's anion is more stable because chlorine is more electronegative and is more stable (via delocalization) than HOI.

[405098546]

Cl bonds have more stability due to higher electronegativity.

[davidryan3f]

Cl is considerably more electronegative than I, so the O-H bond is stronger than the O-I bond. therefore it is a stronger acid.
