The correct order of increasing bond angles in 

  • Cl2O < ClO2 < ClO2-

  • ClO2 <Cl2O< ClO2-

  • Cl2O < ClO2- < ClO2

  • ClO2- < Cl2O < < ClO2

Solution

D.

ClO2- < Cl2O < < ClO2

As the number of lone pair of electrons increases, bond angle decreases due to repulsion between lp-lp. Moreover, as the electronegativity of the central atom decreases, bond angle decreases. Hence, the order of bond is

 
(Cl is less electronegative as compared to O.)
