QAIPMT-2007-Ch-2286: NEET 2007 Chemistry - Class 11 AIPMT-2007-Ch-2286 Solution: The correct order of C-O bond length among CO, \(CO_3^{2-}\),…

The correct order of C-O bond length among CO, CO32−CO_3^{2-}, CO2CO_2 is

Multiple Choice Options

  • A CO<CO32−<CO2CO<CO_3^{2-}<CO_2
  • B CO32−<CO2<COCO_3^{2-}<CO_2<CO
  • C CO<CO2<CO32−CO<CO_2<CO_3^{2-}
  • D CO2<CO32−<COCO_2<CO_3^{2-}<CO

Step-by-Step Verified Solution

All these structures exhibits resonance and can be represented by the following resonating structures. More single bond character in resonance hybrid, more is the bond length. Hence the increasing bond length is CO < CO 2 < CO 3 2 _
