Is butanoic acid stronger than propanoic acid?

But I found a table of Ka for different acids, and it writes that Ka for propanoic acid is 1.34×10−5 while butanoic acid’s acidic constant is 1.48×10−5. This means that butanoic acid is stronger than propanoic acid, but isn’t this a contradiction to the inductive effect? – M.A.R.

Is most acidic among acetic acid propanoic acid butanoic acid Formic acid?

Among formic acid,acetic acid, propanoic acid and phenol the strongest acid in water is. formic acid is strongest Acid.

Which is more acidic between acetic acid and propanoic acid?

It gives electrons to carboxylate ion , destabilize it and decreases the acidity of carboxylic acids carrying bigger alkyl groups. So, acetic acid is more acidic than propanoic acid. Ethanoic (or acetic) acid has a pKa of 4.76. Propanoic acid is slightly more basic (or less acidic) than Ethanoic (acetic) acid.

Which is more acidic formic acid acetic acid or propionic acid?

Formic acid> acetic acid >propionic acid. It is because of the indutive effect. Longer hydrocarbon chain would push more electrons towards the carboxylic group, and hence release of proton ( H+) would be difficult, and easier the release of proton, stronger the a acid.

Why formic acid is stronger acid than acetic acid?

When both compounds are compared, the methyl group is more electron donating than the hydrogen atom. But in acetic acid, its conjugate base, i.e. acetate anion has a methyl group. It has the ability to destabilize the negative charge on the oxygen. Hence we can say that formic acid is more acidic than acetic acid.

Why formic acid is stronger than propanoic acid?

Formula of acetic acid is $C{{H}_{3}}COOH$ that of propanoic acid is ${{C}_{2}}{{H}_{5}}COOH$ and formic acid is HCHO. Here, formic is a stronger acid because the delocalization of negative charge after losing proton is more delocalized in formate ions on two oxygen atoms.

Why CH3COOH is a stronger acid than ch3ch2cooh?

Resonance is a third factor that influences acidity. and acetic acid, we note that the latter is more acidic than the former. that the conjugate base of acetic acid enjoys resonance stabilization, whereas that of ethanol does not. CH3CH2O¯, so CH3COOH is a stronger acid than CH3CH2OH.
