Question

Which of the following species has tetrahedral geometry ?
A. `BH_(4)^(-)`
B. `NH_(2) ^(-)`
C. `CO_(3) ^(2-)`
D. `H_(3) O^(+)`

Answer 1

Correct Answer - A
`BH_(4)^(-)` = trtrahedral , `NH_(2)^(-)` = V-shape , `CO_(3)^(2-)` = tringular planar, `H_(3)O ^(+)` = pyamidal ( Follow the method
given in Table 4.7 or on page 4/52).
