Why picric acid is stronger acid than acetic acid?
Picric acid is 2, 4, 6-trinitrophenol. It, due to presence of three −I showing −NO2 groups, is more acidic than acetic acid and benzoic acid.
Why is picric acid a strong organic acid a1?
4.2. It is well known that picric acid behaves as a strong acid because of the three nitro-groups on the benzene ring.
Which is the strongest acid and why?
For instance, hydrochloric acid comes in at about pH 1.6, nitric acid at 1.08 and pure sulfuric acid at a whopping pH -12. That makes sulfuric acid the strongest ‘normal’ acid you’ll find.
Is picric acid stronger than Sulphuric acid?
Carboxylic acids: The weak organic acids (formic, acetic, etc.). Picric acid. Superacids: Stronger than pure sulfuric acid. Superbases have greater affinities for protons than the hydroxide ion.
Why carbonic acid is stronger acid than phenol?
We can easily observe that carbonic acid forms bicarbonate ion and phenol forms phenoxide ion after losing H+ ion. Bicarbonate ions have two and phenoxide ions have four resonance structures. We can conclude that phenol is an acid weaker than carbonic acid. Therefore, the correct option is (C).
Is carbolic acid a strong acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water….Strong and Weak Acids and Acid Ionization Constant.
| Acid | |
|---|---|
| Strong Acids | |
| HCl (hydrochloric acid) (strongest) | Cl− (chloride ion) (weakest) |
| H2SO4 (sulfuric acid) | HSO−4 (hydrogen sulfate ion) |
Which acid is used for explosives?
Uses. Picric acid is used in the production of explosives, matches, and electric batteries.
Which compound is most acidic?
Hence, picric acid, also known as – 2,4,6,-trinitrophenol – will be the strongest acid!
What determines a strong acid?
Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than a hydronium ion, so its pKa must be lower than that of a hydronium ion. Therefore, strong acids have a pKa of <-174. Strong acids must be handled carefully because they can cause severe chemical burns.
What makes a strong acid strong?
Bond Strength Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak. Strong acids easily break apart into ions. Weak acids exist mostly as molecules with only a few ions in solution, therefore the bonds holding H and A together must be strong.
Why carboxylic acid is stronger than alcohol?
Why is a carboxylic acid more acidic than alcohol? Answer: Resonance always stabilizes a molecule or ion, even if charge is not involved. A carboxylic acid is, therefore, a much stronger acid than the corresponding alcohol, because, when it loses its proton, a more stable ion results.
Which is stronger acid phenol or carbonic acid?
We can conclude that phenol is an acid weaker than carbonic acid. Therefore, the correct option is (C).
