Question

The correct order of increasing bond angles in the following species is

Options

A.Cl2O < ClO2 < ClO2-
B.ClO2 < Cl2O < ClO2-
C.Cl2O < ClO2- < ClO2
D. ClO2- < Cl2O < ClO2

Solution

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

(Cl is less electronegative as compared to O.)
