Bonding in 'gaseous' hydrogen halides??!

Can someone please explain why the 'bonding in gaseous hydrogen halides is best described as mainly covalent with an increasing tendency towards ionic as you go up the group' :s-smilie:

It means the hydrogen - halogen bond.

This further down you go the less the difference in electronegativity and the more covalent. Go up more difference and greater tendency towards ionic character (charge separation)

Is this required for the AQA board, because this doesn't ring a bell. Our teacher told us to self-teach this entire chapter during holiday so sorry for the lame question.
