1.	A colourless liquid 'A' contains H and O elements only. It decomposes slowly on exposure to light. 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» Solution :SINCE a colourless liquid 'A' contains only H and O and decomposes slowly on EXPOSURE to LIGHT but is stabilised by addition of urea, therefore , liquid A may be HYDROGEN peroxide. (i) `2H_(2)O_(2) OVERSET(hv)to 2H_(2)O+ O_(2)`.
