1.	How would you account for the following: (i) Sulphur hexafluoride is less reactive than sulphur tetrafluoride. (ii) Of the noble gases only xenon forms known chemical compounds.
Answer» Solution : (i) `SF_6` is more stable DUE to LESS repulsion in `SF_6` as compared to `SF_4` (II) It is due to large atomic SIZE and high polarisability of Xenon. Xenon has comparatively smallionisation ENTHALPY.
