Q. Among the species:$CO_{2},CH_{3}COO^{-},CO,CO_{3}^{2 -},$HCHO which has the weakest $C - O$ bond?
A) CO
B) $CO_{2}$
C) $CO_{3}^{2 -}$
D) $CH_{3}COO^{-}$
Explanation
(c)
Among the given species, the bond dissociation energy of $C - O$ bond is minimum in case of $CO_{3}^{2 -}$ by which $C - O$bond become more weaker in $CO_{3}^{2 -}$ or the bond order of $CO_{3}^{2 -}(1.33)$ is minimum so, the bond become weaker
