Pls give correct explaination


Dear Student,

The increasing order of bond angle is as follows:

ClO2- < Cl2O < ClO2

Bond angles are as follows:

ClO2-  : 110o

Cl2O: 110.88o

ClO2  : 117.40o

ClO2 has 7+6+6+1=20 total valence electrons to distribute.

ClO2 has 7+6+6=19 total valence electrons to distribute.

Cl2O has oxygen at the center (with chlorine having its typical valency as a halogen), and has 7+7+6=20 total valence electrons to distribute. 

Hence Correct option is (d)
ClO2- < Cl2O < ClO2.
