Pick out the incorrect statement for CIO_(3)

Answer»

`CIO_(2)` is a powerful oxidizing and chlorinating agent and is prepared in the laboratory from `NaCIO_(3)` and oxalic acid.
`CIO_(2)`, is used to manufacture `NaCIO_(2)` , which is also used for bleaching textiles and paper.
`CIO_(2)` COMBINES with `O_(3)` to FORM dichlorine HEXOXIDE, a dark red liquid.
`ClO_(2)` contains an odd number of ELECTRONS and therefore, it dimerizes like `NO_(2)`

SOLUTION :`CIO_(2)` molecules is paramagnetic and contains an odd number of electrons. Odd electron molecules often dimerize in order to pair the electrons, but `CIO_2` does not dimerize. This is because odd electrons is delocalized. The molecule is angular with O-Cl-O angle of `108^(@)`. The bond of lengths are both 147 pm and are shorter than for single bonds.
`2NaClO_(3)+2(COOH)_(2) overset(H_(2), 90^(@)C)to 2ClO_(2)+2CO_(2)+(COONa)_(2)+2H_(2)O`
`(b) 2ClO_(2)+2NaOH+H_(2)O_(3) to 2NaClO_(2)O_(3)+2H_(2)O`
(c) `2ClO_(3)+2O_(3) to Cl_(2)O_(6)+2O_(3)` .
