Chemical Bonding And Molecular Structure Question 356

Question: The bond order in $ CO_3^{2-} $ ion between $ C-O $ is [Pb. PMT 2004]

Options:

A) Zero

B) 0.88

C) 1.33

D) 2

Show Answer

Answer:

Correct Answer: C

Solution:

We know that carbonate ion has following resonating structures Bond order $ =\frac{\text{Total number of bonds between atoms}}{\text{Total number of resonating structure}} $

$ =\frac{1+1+2}{3}=\frac{4}{3}=1.33 $ .
