Answer» Hydrides of halogens : Formation : `H_(2)+F_(2)overset("dark condition")to2HF` `H_(2)+Br_(2)overset("593 K")to2" HBr"` `H_(2)+Cl_(2)overset("Sun light")to2" HCl"` `H_(2)+I_(2)overset("713 K")to2" HI"` `to` These compounds dissolve in water to form hydrohalic acids. `{:(to,"Boiling points",,HF,,-,293" K"),(,,,HCl,,-,189" K"),(,,,HBr,,-,206" K"),(,,,HI,,-,238" K"):}` `to` The decreasing order of stability of these compounds is `HF gt HCl gt HBr gt HI` `to` The increasing order of acicid strength of these compounds `HF lt HCl lt HBr lt HI` |
