(a) Account for the following :
(i) Hydration enthalpy of ion is more than ion.
(ii) is a reducing agent, whereas is an oxidising agent in group oxides.
(b) Write the reaction of with water. Why does not react with water ?
(c) Draw the structure of .
a)
i) Hydration enthalpy of ion is more than ion because of smaller size of F – ion than Cl– ion
ii) is a reducing agent, whereas is an oxidising agent in group oxides because sulphur is more stable in +6 state and Tellurium is more stable in +4 state
b) 2F2 + 2H2O -------> 4HF + O2
I2 doesnot react with water because I2 is a weak oxidizing agent.
