HF is less reactive due to the very strong bond between hydrogen and a halogen (Florine) which doesn't dissociates easily. A strong bond does not allow this acid to react easily.
The reactivity of halogen acidsincrease as the size of halogen atom increases down the group. And the inertness increases as we move to top from bottom in a group of halogens.
HCl is more reactant than HF due to the large size of Cl atom and due to the large size of Cl atom, the bond between H and Cl is weak so it dissociates easily. This makes it more reactive.
The reactivity of halogen acids is:
HF
Hydrogen fluoride (HF) has a larger size than hydrogen chloride (HCl) because fluorine is more electronegative than chlorine and hence exerts a stronger pull on the shared electrons in the HF molecule, causing the atoms to be closer together and giving the molecule a larger size. Additionally, the presence of hydrogen bonding in HF also contributes to a larger overall size compared to HCl.
Hydrogen fluoride (HF) has a higher boiling point than hydrogen chloride (HCl) because HF molecules are polar, allowing them to form stronger hydrogen bonds compared to the dipole-dipole interactions in HCl. This results in a stronger intermolecular attraction in HF, requiring more energy to overcome and hence a higher boiling point.
HCl is a strong acid, while NaOH, HF, and NH3 are not strong acids. NaOH is a strong base, HF is a weak acid, and NH3 is a weak base.
The reaction HCl + F2 --> HF + Cl2 is a redox reaction, specifically a single replacement reaction. Hydrogen chloride (HCl) reacts with fluorine (F2) to produce hydrogen fluoride (HF) and chlorine (Cl2).
Boiling point of HCl: -85,1 0C. Boiling point of HF: 19,5 0C.
with HCl the reaction is endothermic and homolysis of HCl does not occur as the effect follows free radical mechanism. The homolysis of HI occurs but the i radical forms iodine molecule and also it's activation energy is high.

The pKa of hydrofluoric acid (HF) is approximately 3.17. This indicates that HF is a weak acid, meaning it does not fully dissociate in water. Its relatively low pKa value reflects its ability to donate protons, but its strength is significantly less than that of strong acids like hydrochloric acid (HCl).

due to more h-bonding in water as compared to Hf
due to more h-bonding in water as compared to Hf
The chemical formula for Hydroflouric acid is HF It is not a very reactive acid but Fluorine,which is in this acid is very reactive
Yes, it is true: -85,1 0C at 1, 013 bar.
