Find out the oxidation number of chlorine in the following compounds and arrange them in increasing order of oxidation number of chlorine. NaClO_(4), NaClO_(3), NaClO, KClO_(2), Cl_(2)O_(7), ClO_(3), Cl_(2)O, NaCl, Cl_(2), ClO_(2) . Which oxidation state is not present in any of the above compounds?

Draw structure Cl_(2)O_(7)

For 1 molal solution of each compound minimum freezing point will be assuming compound ionisation in each case : (a) [Fe(H_(2)O)_(6)]Cl_(3) (b) [Fe(H_(2)O)_(5)Cl]Cl_(2) . H_(2)O (c) [Fe(H_(2)O)_(4)Cl_(2)]Cl .2 H_(2)O (d) [Fe(H_(2)O)_(3)Cl_(3)] .3 H_(2)O

Increasing order of bond angle of (Cl_(2)O, ClO_(2), Cl_(2)O_(7), I_(3)^(ɵ)) is
