Which of the following species does not have tetraahedral geometry ?A. `BH_(4)^(-)`B. `NH_(2)^(-)`C. `CO_(3)^(2-)`D. `H_(3)O^(+)` |
|
Answer» Correct Answer - C `BH_(4)^(-):H=^(1//2)[5+4-1+0]=4(sp^(3))` `NH_(2)^(-):H=^(1//2)[5+2-0+1]=4(sp^(3))` `CO_(3)^(2-):H=^(1//2)[4+0-0+2]=3(sp^(2))` `OH_(3)^(+):H=^(1//2)[6+3-1+0]=4(sp^(3))` `CO_(3)^(2-)` ion has trigonal geometty. |
