In order to form hydrogen bonds a molecule should have a hydrogen tht is DIRECTLY attched to an elctronegative element such as oxygen,fluorine or nitrogen.In haloalkanes we dont have a hydrogen attched to an elctronegatve element , even if u consider some haloalkane with flurorne in it u would say it should form h- bonds but no it doest as F is not atthched to hydrogen rather a Carbon which in turn is attched to hydrogen but as i told in order for h-bonds to form Flourine should be DIRECTLY bonded to a hydrogen.
