A) \[CO_{3}^{2-}<C{{O}_{2}}<CO\]
B) \[CO_{2}^{{}}<CO_{3}^{2-}<CO\]
C) \[CO<CO_{3}^{2-}<C{{O}_{2}}\]
D) \[CO<CO_{2}^{{}}<CO_{3}^{2-}\]
Correct Answer: D
Solution :
B.O. in CO, i.e.,: \[C=O\]: is 3, that of \[\operatorname{O}=C=O\] is 2 while that of \[C{{O}^{2-}}_{3}\] ion is 1.33. Since the bond length increases as the bond order decreases, i.e., \[\operatorname{CO} < C{{O}_{2}} < C{{O}^{2-}}_{3}\]. Thus option is correct.You need to login to perform this action.
