Q. The correct order of increasing bond angles in the following species is
AIPMTAIPMT 2010The p-Block Elements - Part2
Solution:
The correct order of increasing bond angles in the following species is $$ Cl _{2} O < ClO _{2}^{-}< ClO _{2} $$ This is because, In $ClO _{2}^{-}$there are two lone pairs of electrons which repel each other due to which two oxygen atom come closer leading to decrease in bond angle. Therefore the bond angle in $ClO _{2}^{-}$is less than $118^{\circ}$ which is bond angle in $ClO _{2}$ which has less number of electrons on chlorine.
