The correct order of increasing radii of the ions Br^(-), F^(-), O^(2-) and S^(2-) is as follows

Answer»

`Br^(-)ltF^(-)ltO^(2-)ltS^(2-)`
`S^(2-)ltO^(2-)ltF^(-)LTBR^(-)`
`F^(-)ltO^(2-)ltS^(2-)ltBr^(-)`
`F^(-)ltBr^(-)ltO^(2-)ltS^(2-)`

SOLUTION :`F^(-)` and `O^(2-)` are ISOELECTRONIC but NUCLEAR charge of `F^(-)gtO^(2)`. Hence, ionic radius of `F^(-)ltO^(2-)`. So the order is `F^(-)ltO^(2-)ltS^(2-)ltBr^(-)`.
