question_answer 1)

  A colourless liquid ?A' contains H and O elements only. It decomposes slowly on exposure to light. It is stabilised by mixing urea to store in the presence of light. (i) Suggest possible structure of 'A? (ii) Write chemical equations for its decomposition reaction in light.

Answer:

  (i) The compound is\[{{H}_{2}}{{O}_{2}}\]. Its structure is (ii) Decomposition by light \[2{{H}_{2}}{{O}_{2}}\to 2{{H}_{2}}O+{{O}_{2}}\]
