1.	In which of the following pairs, the two species are lso-structure ?
Answer» `SO_(3)^(2-) and NO_(3)^(-)`<BR>`BF_(3) and NF_(3)` `BrO_(3)^(-) and XeO_(3)` `SF_(4) and XeF_(4)` Solution :`BrO_(3)^(-) and XeO_(3)` HYBRIDIZATION of Br is `BrO_(3)^(-)` Total valence electrons = 7 + 3 `xx 6 ` = 25 Charge = -1 hence Total 25 +1 = 26 `= (26)/(8) = 3 ` (Q) + 2 (R) = 5 Hybridization= `dsp^(3)` Hybridization of Xe in` XeO_(3)` Total valence electrons = 8 + 3 `xx 6` = 26 = ` (26)/(8) = 3 (Q) + 2 (R) = 5 ` Hybridization = `dsp^(3)` In both cases , the structure is TRIGONAL pyramidal.
