Question

The oxides of chlorine, bromine and iodine are well known. They have various compositions. The oxides of chlorine are thermally unstable and dangerously explosive. They react with alkali. The bromine oxides are thermally more stable than chlorine oxides. The structure of halogen oxides is explained on the basis of VSEPR theory.

The structure of $C{l}_2{O}_7$ is $O_{3}Cl-O-Cl{O}_3$ The Cl - O-Cl bond angle is:

• A. ${180}^0$
• B. ${119}^0$
• C. ${109}^0{28}^{\prime }$
• D. ${108.7}^0$

Answer 1

The correct option is B

${119}^0$

$O$ in $O_{3}Cl-O-Cl{O}_3$ is $s{p}^3$-hybridized and due to bulky $O_{3}Cl-$ group. The bond angle is larger than ${109}^0{28}^{\prime }$.
