Which is more acidic between benzoic acid or acetic acid?

Which is more acidic between benzoic acid or acetic acid?

Assertion :Benzoic acid is stronger acid than acetic acid. Reason: Ka for benzoic acid is 6.5×10−5 and for acetic acid is 1.74×10−5.

What is pKa of benzoic acid?

The literature pKa value of benzoic acid is 4.2 and for m-chlorobenzoic acid, the pKa value is 3.77 (determined in water).

Which is more acidic between acetic acid and benzoic acid give reasons?

The pKa of ethanoic acid is 4.75 and that of benzoic acid is 4.2. Benzoic acid is more acidic because of the electron withdrawing nature of the benzene ring structure.

What is the actual pKa of acetic acid?

For example, the Ka constant for acetic acid (CH3COOH) is 0.0000158 (= 10-4.8), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid.

Why does benzoic acid have lower pKa than acetic acid?

Benzoic acid itself is a somewhat stronger acid than acetic acid. The carboxyl group of benzoic acid is attached to an sp2-hybridized carbon which is more electronegative and electron-withdrawing than the sp3-hybridized carbon attached to acetic acid.

Which is stronger acid c6h5cooh and ch3cooh?

Stronger acids have lower pKa value. The ethanoic acid (pKa = 4.76) is weaker acid than benzoic acid (pKa = 4.19 ).

Why does benzoic acid have a lower pKa than acetic acid?

Which has lower pKa than benzoic acid?

p-nitrobenzoic acid has lower pka value than benzoic acid.

Why benzoic acid has highest pKa value?

In benzoic acid , there is only one -COOH group. Therefore, its pKa value is higher than that of salicylic acid. Hence phenol has the lowest acidity and highest pKa value due to its single -OH group.

Which is more acidic carboxylic acid or benzoic acid?

Formic acid is stronger than benzoic acid because it has a lower pKa value. Formic acid does not have such a group of electron donors and is stronger than acetic acid. Formic acid is also a stronger acid than acetic acid.
