Current Question (ID: 8000)

Question:

The correct order of 'S—O' bond length is:

Options:

1. $SO_3^{2-} > SO_4^{2-} > SO_3 > SO_2$
2. $SO_3^{2-} > SO_4^{2-} > SO_2 > SO_3$ (Correct)
3. $SO_4^{2-} > SO_3^{2-} > SO_2 > SO_3$
4. $SO_4^{2-} > SO_3^{2-} > SO_3 > SO_2$

Solution:

HINT: Bond order $\propto \frac{1}{\text{bond length}}$ Explanation: The relation between bond length and bond order is shown below: Bond order $\propto \frac{1}{\text{bond length}}$ Higher the resonance, higher will be the bond length of double bond or triple bond. The bond length of $SO_2 = 143 \text{ pm}$ The bond length of $SO_3 = 142 \text{ pm}$ B. O. = $\frac{4}{3} = 1.33$ B. O. = $\frac{6}{4} = 1.5$ $SO_3^{2-} > SO_4^{2-} > SO_2 > SO_3$
