Explain the following :
(a) Xenon does not form such fluorides as and .
(b) Out of noble gases, only Xenon is known to form real chemical compounds.
How is obtained? Write the related chemical equations. Draw the structure of

(i) C + conc.
How would you account for the following:
(i) is an endothermic compound while is an exothermic one.
(ii) is a linear molecule without a bend.
(iii) The electron gain enthalpy with negative sign for fluorine is less than that for chlorine, still fluorine is a stronger oxidising agent than chlorine.
