The Xenon  and Krypton atom are larger than the other noble gasses so its outer electrons are farther away from the nucleus and thus a little more loosely held making them subject to interaction with strong electron acceptors. One exception to the above is Radon whose atom is even larger. However Radon is radioactive with a short half life so even though it probably is more reactive, its compounds would not last long.
