Which of the two ions from the list given below that have the geometry

1.	Which of the two ions from the list given below that have the geometry that is explained by the same hybridization of orbitals , NO_(2)^(-), NO_(3)^(-), NH_(2)^(-), NH_(4)^(+), SCN^(-) ?
Answer» `NO_(4)^(+) and NH_(2)^(-)` `NO_(2)^(-) and NO_(3)^(-)` `NH_(4)^(+) and NO_(3)^(-)` `SCN^(-) and NH_(2)^(-)` SOLUTION :Applying ` X= (1)/(2) [VE + MA - c + a) ` `NO_(2)^(-) to SP^(2), NO_(3)^(-) to sp^(2)` ` NH_(2)^(-) to sp^(3), NH_(4)^(+) to sp^(3)`, ` SCN^(-) to sp `
