Chemical Bonding And Molecular Structure Question 39
Question: Among the species : $ CO_2,CH_3CO{O^{-}}, $ $ CO,CO_3^{2-}, $ HCHO which has the weakest carbon- oxygen bond [Kerala PMT 2004]
Options:
A) $ CO_2 $
B) $ CH_3CO{O^{-}} $
C) CO
D) $ CO_3^{2-} $
E) HCHO
Show Answer
Answer:
Correct Answer: D
Solution:
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.
