Question

What is the bond angle between $Cl-O-Cl$ in $C{l}_2{O}_7$ ?

• A. ${109}^o$
• B. ${119}^o$
• C. ${108}^o{25}^{\prime }$
• D. ${120}^o$

Answer 1

Answer: (B)

${119}^o$

$C{l}_2{O}_7$ has a bent structure with a bridging $O-$atom. The terminal $Cl-O$ bonds are substantially shorter than the bridge $Cl-O$ bonds, indicating double bond character.
