(i) NCl3 is an endothermic compound while NF3 is an exothermic one.
(ii) XeF2 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.

(i) This is because of (a) bond dissociation enthalpy of F2 is lower than Cl2 and (b) fluorine forms stronger bond with nitrogen due to comparable size.
(ii) As xenon is sp3 hybridised with three lone pair of electrons.
(iii) This is due to (a) low bond dissociation enthalpy of F2 and (b) high hydration enthalpy of F- .
