The correct order of \(\mathrm{C}-\mathrm{O}\) bond length in \(\mathrm{CO}, \mathrm{CO}_3^{2-}\), \(\mathrm{CO}_2\) is
- A \(\mathrm{CO} < \mathrm{CO}_3^{2-} < \mathrm{CO} 2\)
- B \(\mathrm{CO}_3^{2-} < \mathrm{CO}_2 < \mathrm{CO}\)
- C \(\mathrm{CO} < \mathrm{CO}_2 < \mathrm{CO}_3^{2-}\)
- D \(\mathrm{CO}_2 < \mathrm{CO}_3^{2-} < \mathrm{CO}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CO} < \mathrm{CO}_3^{2-} < \mathrm{CO} 2\)
Step-by-step Solution
Detailed explanation
\(\mathrm{O}=\mathrm{C}=\mathrm{O} ;{ }^{\ominus} \mathrm{C} \equiv \mathrm{O}^{\oplus}\) The bond length is smallest for the \(\mathrm{C} \equiv \mathrm{O}\) bond due to strong triple bond. Among \(\mathrm{CO}_3^{2-}\) and \(\mathrm{CO}_2, \mathrm{CO}_3^{2-}\) has the smaller…
