Question
Which is true about ozone ?
Options
A.It turns filter paper soaked in alcoholic benzidine to brown colour.
B.It is used for detecting the position of double bond in unsaturated organic compound.
C.It forms a solid I4O9 with dry iodine (I2)
D.All of these
Solution
(A) A filter paper soaked in a alcoholic benzidine 
becomes brown when brought in contact with O3.
(B) For detecting the position of double bond in the unsaturated organic compounds via reductive ozonolysis.
(C) 2I2 + 9[O3] → I4O9 + 9O2 ; I4O9 yellow solid has the composition I+3 (IO3-)3.
