Answer» Solution : (i) In HF, there are intermolecular H-bonds. .. it has high b. pt. and is liquid at ROOM temperatures.  In HCl, there are weak VAN der Waals. forces of attractions. ` therefore ` There are weak van der Waals. forces of attraction, . it has low b.pt. and is gas at room temperature. (II) The increasing order of ACIDIC strength is :HF |
