How does the addition of O atoms to a Carboxylic acid help s

How does the addition of O atoms to a Carboxylic acid help stabilize the conjugate base, and why does stabiliizing the conjugate base increase the acidity of the Carboxylic acid?

Solution

more stable is conjugate base more easily it will form by removable of proton therefore stronger is the acid

HA----->H+ + A-

If stability of A- (conjugate base ) increases reaction shift to left that is stable side

hence we can say that stability of conjugate base is proportional to acidic strength

part first

O has negative inductive effect so it withdraw electron cloud from conjugate base hence stablises negative charge

therefore increasers acidic strength
