The correct order of $'S-O'$ bond length is
$SO^{2-}_3 > SO^{2-}_4 > SO_3 > SO_2$
$SO^{2-}_3 > SO^{2-}_4 > SO_2 > SO_3$
$SO^{2-}_4 > SO^{2-}_3 > SO_2 > SO_3$
$SO^{2-}_4 > SO^{2-}_3 > SO_3 > SO_2$
Explain why ${\rm{CO}}_3^{2 - }$ ion cannot be represented by a single Lewis structure. How can it be best represented ?
Draw the resonating structure of $(A)$ Ozone molecule $(B)$ Nitrate ion
Resonance is due to
Which of the following conditions is not correct for resonating structures?
A molecule may be represented by three structures having energies $E_1 , E_2$ and $E_3$ , respectively. The energies of these structures follow the order $E_3 < E_2 < E_1$ , respectively. If the experimental bond energy of the molecule is $E_0$ , the resonance energy is
