SATHEE: Chemical Bonding And Molecular Structure Question 39

Chemical Bonding And Molecular Structure Question 39

Question: Among the species : $C O_{2}, C H_{3} C O O^{-},$ $C O, C O_{3}^{2 -},$ HCHO which has the weakest carbon- oxygen bond [Kerala PMT 2004]

Options:

A) $C O_{2}$

B) $C H_{3} C O O^{-}$

C) CO

D) $C O_{3}^{2 -}$

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 $C O_{3}^{2 -}$ by which $C - O$ bond become more weaker in $C O_{3}^{2 -}$ or the bond order of $C O_{3}^{2 -}$ (1.33) is minimum so the bond become weaker.
