What is the bond angle between \[\text{Cl-O-Cl}\] in\[C{{l}_{2}}{{O}_{7}}\]?

A) \[~\text{1}0\text{9}{}^\circ \]                                   

B) \[\text{119}{}^\circ \]   

C) \[{{108}^{\circ }}25'\]                     

D) \[\text{12}0{}^\circ \]

Correct Answer: B

Solution :

\[C{{l}_{2}}{{O}_{7}}\]has a bent structure with a bridging O-atom. The terminal \[\text{Cl}\text{O}\] bonds are substantially shorter than the bridge \[\text{Cl}\text{O}\] bonds, indicating double bond character.
