The correct of increasing bond angles in the following species is

1.	The correct of increasing bond angles in the following species is
Answer» `CIO_(2)^(-) lt Cl_(2)O lt ClO_(2)` `Cl_(2)O lt ClO_(2) lt ClO_(2)^(-)` `ClO_(2) lt Cl_(2)O lt ClO_(2)^(-)` `Cl_(2)O lt ClO_(2)^(-) lt ClO_(2)` Solution : In `ClO_(2), Cl is sp^(2)` -hybridized and the bond ANGLE is `180^(@)` . In `Cl_(2)O,OIS sp^(3)` -hybridized . HOWEVER , dueto repulsions between two BIG sized Cl atoms, the bond angle increases from `109.5^(@)` to `111^(@)` . In `ClO_(2)^(-) ,Cl` ATOM is `sp^(3)`-hybridizedbut due to lp-bp repulsions, the angle decreases from `109.5^(@)` to `103^(@)` .Thus, the increasing order of bond angles is `ClO_(2)^(-) lt Cl_(2)O lt ClO_(2)`.
