Which is the stronger acid HF or HCl?, You are correct, HCl is a stronger acid than HF. Fluorine is both more electronegative and smaller than chlorine. Because fluorine is more electronegative, the bond between it and the hydrogen is more polar, meaning that the proton would need to overcome a larger coulomb force to separate from the fluorine.
Furthermore, Which is the strongest acid HF HCl HBr hi?, Acid Strength and Bond Strength
HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5).
Finally, Which of the following compounds is the weakest acid HF HCl HBr hi?, Since H−I bond is weakest, therefore, HI is the strongest acid. On the other hand H-F bond is strongest, hence it is the weakest acid among all the halogen acids.
Frequently Asked Question:
Why HF is the weakest acid and HI is the strongest?
In HI iodine is less electronegative and it has large size. Therefore bonding between hydrogen and iodide is weaker. It will easily split in comparision of HF. Due to more liberation of H+ ions HI is stronger acid.
Why HF is a weaker acid than hi?
The bond length of HF is very small and HF is more electronegative element while the bond length of HI is very very big and HI less electronegative element. Thus HF is weaker than HI in acetic acid.
Which is stronger acid HF or hi?
HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5). … Shorter bonds are more stable, and thus the H-F bond is more difficult to break.
Why HI is more stronger than HF?
Bond strength is related to the length of the bond, and because Iodine has a much larger atomic radius than Fluorine, HI has a much longer, and therefore weaker, bond. The hydrogen is removed fairly easily, making HI a stronger acid.
Why is HF considered a weak acid while HCl HBr and HI are strong acids?
Fluorine is highly electronegative, so the bond in HF is a polar covalent bond. The more polar a bond is, the easier it is to remove the proton or hydrogen from the acid. So, hydrochloric acid (HCl) is a stronger acid than hydrobromic acid (HBr). Based only on its polarity, one might expect HF to be stronger than HCl.
Which bond is the weakest HBr HCl HF hi?
1 Answer. There is a single covalent bond between hydrogen and the halogen. H−I is both longer and weaker.
Which has the lowest boiling point HF HCl HBr hi?
HF shows H-bonding possess a higher boiling point or less volatile nature. HCl has the least boiling point due to the small dispersion intermolecular forces. HCl < HBr < HI < HF.
Why is HF weaker acid than hi?
In HI iodine is less electronegative and it has large size. Therefore bonding between hydrogen and iodide is weaker. It will easily split in comparision of HF. Due to more liberation of H+ ions HI is stronger acid.

Which has the highest boiling point HF HCl HBr hi?
∵ H-F molecule forms strong intermolecular hydrogen bonding , so it has highest boiling point among HF ,HCl, HBr and HI, HCl, HBr and Hi are held together by weaker van der Waal’s forces and have lower boiling point.
Why HF is a weaker acid than HCl?
HF is a weaker acid because the strength of an acid is determined by how completely that acid will dissociate. Since the bond between HF is stronger than the bond between HCl, HCl will more completely dissociate which makes it a stronger acid.
Which one is stronger acid HF and HCl Why?
Answer. Answer: Hydrogen chloride (HCL) is more acidic than HF because cl is more electronegative than Floridr And hence it can donate H+ more easily than Florine {F} .
Which is a stronger acid HI or HF?
Acid Strength and Bond Strength
HCl, HBr, and HI are all strong acids, whereas HF is a weak acid.
Why is HF not a strong acid?
However, it is a weak acid and not a strong acid because it does not completely dissociate in water (which is the definition of a strong acid) or at least because the ions it forms upon dissociation are too strongly bound to each other for it to act as a strong acid.
