Which is more acidic P nitrophenol or salicylic acid?

Which is more acidic P nitrophenol or salicylic acid?

Salicylic acid is much stronger than p-hydroxy benzoic acid but acidity of o-nitrophenol and p-nitrophenol is almost same-explain. Salicylic acid is much Stronger than p-hydroxy benzoic acid but acidity of o-nitrophenol and p-nitrophenol is almost same-explain.

Which is more acid para hydroxybenzoic acid?

Ortho hydroxybenzoic acid is more acidic than para hydroxybenzoic acid because, the lower the pka value increases the acidity of that compound and higher the pka value decreases the acidity of that compound. Ortho hydroxybenzoic acid (pka=2.98), para hydroxybenzoic acid (pka=4.58).

Which acid is most acidic amongst?

For example, hydrogen chloride is a strong acid in aqueous solution, but is a weak acid when dissolved in glacial acetic acid….Strong acids.

Which of the following p substituted acid is most acidic?

Option B is p-hydroxybenzoic acid, here also hydrogen is attached with oxygen, of hydroxide group but because p-hydroxybenzoic acid is itself an acid and the hydrogen will release from more acidic hydrogen that is from carboxylic acid group. Hence, it will be more acidic than phenol.

Why salicylic acid is stronger acid than p-hydroxybenzoic acid?

In salicylic acid, the major effect is hydrogen bonding by the phenolic OH group to the carboxyl group. This removes electron density from the carboxylic acid, making its hydrogen more acidic.

Why M hydroxybenzoic acid is stronger than p-hydroxybenzoic acid?

In case of p-hydroxybenzoic acid, the anion is destabilized by the +M effect of the hydroxy group lying on the p group. Whereas, in m-hydoxy benzoic acid, the hydroxy group does not provide +M effect to the C to which the acidic group is attached. Hence, m-hydoxy benzoic acid is stronger than its para derivative.
