Hydrofluoric corrosive is a powerless corrosive, not at all like the other hydrogen halides, which are solid acids. Fluorine has solid fondness for hydrogen, thus it takes huge measure of vitality to break the solid H-F bond in water. Likewise, on account of the high electronegativity of fluorine, there is broad hydrogen holding in HF.

The high distinction in electronegativity amongst H and F imply that the H-F bond is more grounded than the other H-halide bonds. (the H-Cl bond being the weakest)

This implies HCl totally separates in water, making it a solid corrosive, while HF separates just incompletely in water, making it the weakest corrosive in the arrangement.

Be that as it may, HI is more stronger than HCl. This is on account of the nuclear range of an iota of iodine is much bigger than that of a chlorine particle. Subsequently, the negative charge over the I− anion is scattered over a bigger electron cloud and its fascination for the proton (H+) is not as solid as the same fascination in HCl.
