(a) (i) Write the disproportionation reaction of .
(ii) Draw the structure of
(b) Account for the following:
(i) Although Fluorine has less negative electtron gain enthalpy yet F2 is styrong oxidizing agent.
(ii) Acidic character decreases from N2O3 to Bi2O3 in group 15.
(c) Write a chemical reaction to test sulphur dioxide gas. Write chemical eqaution involved.
(a) (i)
(ii)
(b) (i) Fluorine is the strongest oxidising agent because of:
(ii) The oxides E2O3 of N and P are acidic. As amphoteric and those of Bi basic beacuse the metallic character of the element and hence the basicity of its oxide increases with increasing atomic number.
(c)
SO2 turns a filter paper moistened with acidified potassium dichromate solution green, due to the formation of and acts as a reducing agent.
