1.

(i)Draw the gas phase and solid phase structure of H_2O_2 (ii) H_2O_2 is a better oxidising agent than water. Explain.

Answer»

SOLUTION :(i)`H_2O_2` has a non-planar STRUCTURE .

(ii)`H_2O_2` is a better oxidising agent then water its reasons are of follow `H_2O_2` oxidises an ACIDIFIED solution of KI to give `I_2` which gives blue colour with starch solution but `H_2O` does not.
`2KI+H_2SO_4 + H_2O_2 to K_2SO_4 + 2H_2O + I_2`
`H_2SO_4` TURNS block PbS to white `PbSO_4` but `H_2O`does not.
`PbS+4H_2O_2 to PbSO_4 + 4H_2O`
