how to identify paramagnetic or diamagnetic 1)H2O 2)SO2 3)SO3 4)NH4+ 5)CO2 6)SO2 7)Clo2 8)SiO2 9)HCl and other similar compound which cannot be found using MOT Share with your friends Share 12 Geetha answered this Count the number of valence electron, if its odd its paramagnetic. If its even its diamagnetic.1. H2O = 2 ×1 + 6 = 8 Its diamagnetic2. SO2 = 6 + 2 × 6 = 18 Its diamagnetic3. SO3 = 6 +3× 6 = 24 Its diamagnetic4. NH4+ = 5 + (4 × 1)-1 = 8 Its diamagnetic5. CO2 = 4 + 2 × 6 = 16 Its diamagnetic6. Repeated7. ClO2 = 7 + 2 × 6 =19 - Its paramagnetic8. SiO2 = 4 + 2 × 6 = 16 Its diamagnetic9. HCl = 1 +7 = 8 Its diamagnetic 10 View Full Answer
