Question

Why Ethanoic acid is a weaker acid than Benzoic acid. ​

Answer 1

$\huge\bigstar\underline\mathfrak{Answer:-}$

• The ethanoic acid (pKa = 4.76) is weaker acid than benzoic acid (pKa = 4.19 ).Due to the presence of benzene ring inbenzoic acid, delocalisation of electron makes it more acidic than ethanoic acidbut such stabilization is not present inethanoic acid.
