| Case II: Read the passage given below and answer the following questions from 6 to 10. |
| Under the normal conditions, noble gases are monoatomic and have closed shell electronic configuration. Lighter noble gases have low boiling points due to weak dispersion forces between the atoms and the absence of other interatomic interactions. Xenon, one of the important noble gas, forms a series of compounds with fluorine with oxidation number +2, +4 and +6. All xenon fluorides are strong oxidizing agents. \[Xe{{F}_{4}}\] reacts violently with water to give \[Xe{{O}_{3}}\]. The geometry of xenon compounds can be deduced by considering the total number of electron pairs in their valence shell. |
