1.	In which of the following molecules / ions BF_(3), NO_(2)^(-), H_(2) the central atom is sp^(2) hybridised ?
Answer» `NH_(2)^(-)and H_(2)O` `NO_(2)^(-) and H_(2)O` `BF_(3) and NO_(2)^(-)` `BF_(3)and NH_(2)^(-)` Solution :CENTRAL ATOM `sp^(2)` hybridised `NO_(2)^(-)` - Central stom `sp^(2)` hybridised `BF_(3)` - Central atom `sp^(2)` hybridised `NH_(2)^(-)` - Central atom `sp^(3)` hybridised
