Which of the following pairs of ions in iso-electronic and iso-structural?
- A \(\mathrm{CO}_{3}^{2-}, \mathrm{NO}_{3}^{-}\)
- B \(\mathrm{SO}_{3}^{2-}, \mathrm{NO}_{3}^{-}\)
- C \(\mathrm{ClO}_{3}^{-}, \mathrm{CO}_{3}^{2-}\)
- D \(\mathrm{SO}_{3}^{2-}, \mathrm{CO}_{3}^{2-}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CO}_{3}^{2-}, \mathrm{NO}_{3}^{-}\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{CO}_{3}^{2-}\), total number of electrons \(=32\) In \(\mathrm{NO}_{3}^{-}\), total number of electrons \(=32\) In \(\mathrm{SO}_{3}^{2-}\), total number of electrons \(=42\) So, the option (a) is correct.
