(a) Draw the molecular structures of the following compounds :
(b) Explain the following observations :
(i) Sulphur has a greater tendency for catenation than oxygen.
(ii) ICI is more reactive than
(iii) Despite lower value of its electron gain enthalpy with negative sign, fluorine is a stronger oxidising agent than
Shape : Square pyramidal
(b) (i) It is because S-S bond is stronger than O-O bonds as there is more interelectronic repulsion in O-O due to small size than in S-S.
(ii) ICI is more reactive than because I-Cl bond is polar and weaker while I-I bond is stronger and non-polar.
(iii) It is due to (a) low enthalpy of dissociation of F-F bond, (b) high hydration enthalpy of F.
