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.

ReneHydrofluoric acid (HF) is less reactive than hydrochloric acid (HCl) due to the stronger H-F bond compared to the H-Cl bond. This results in a higher bond dissociation energy for HF, making it less likely to ionize and release H+ ions. Additionally, the fluorine atom in HF is more electronegative than chlorine in HCl, leading to a more stable HF molecule.

Why the size of HF is greater than HCL?
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.
Why has HF higher boiling point than 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.
What is a strong acid NaOH HF NH3 HCl?
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.
What type of reaction is HCl plus F2-HF plus Cl2?
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).
HF HCl boiling temperature?
Hydrochloric acid (HCl) has a boiling point of approximately -85 degrees Celsius. Hydrogen fluoride (HF) has a higher boiling point of approximately 19 degrees Celsius.
