A) \[C{{l}_{2}}O<Cl{{O}_{2}}<ClO_{2}^{-}\]
B) \[C{{l}_{2}}O<C{{l}_{2}}O<ClO_{2}^{-}\]
C) \[C{{l}_{2}}O<ClO_{2}^{-}<ClO_{2}^{{}}\]
D) \[ClO_{2}^{-}<C{{l}_{2}}O<ClO_{2}^{{}}\]
Correct Answer: D
Solution :
Key Idea As the number of tone pairs of electrons increases, bond angle decreases due to repulsion between Ip - Ip. Moreover, as the electro negativity of central atom decreases, bond angle decreases. Hence, the order of bond angle is
(Cl is less electronegative as compared to O.)
