Question

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 $

Answer 1

Answer: (B)

$ 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.
