Multiple Choice QuestionsThe correct order of increasing bond angles in
Cl2O < ClO2 < ClO2-
ClO2 <Cl2O< ClO2-
Cl2O < ClO2- < ClO2
Cl2O < ClO2- < ClO2
D.
Cl2O < ClO2- < 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.)
