Relative Acidity

Postby 205389184 » Sun Dec 01, 2019 11:09 pm

When in reference to relative acidity, what does charge delocalization stabilize? Dr.Lavelle mentioned this in lecture but I was not able to hear the rest of the sentence.

He said that any mechanism that delocalizes charge makes it more stable. This is due to the electron pulling ability of the delocalization mechanism, giving it a higher electronegativity. The higher electronegativity makes it a more stable anion.

Delocalization of electrons lessens the instability caused by having one area of lone pair electrons spreading this out helps.

Delocalizing the charge makes the molecule more stable. For instance, between HClO and HClO4, HClO4 would be the stronger acid since it has more oxygens to delocalize the charge. In terms of these molecules too, the greater number of oxygen atoms attached to the central atom makes the molecule a stronger acid because the oxidation number increases.

oh okay, so the more electronegative the more stable the anion?
