The molecule which has pyramidal shape is

Options

A. `PCI_(3)`
B. `SO_(3)`
C. `CO_(3)^(2-)`
D. `NO_(3)^(Theta)`

Answer

A

Explanation

Hybridisation is
(a) `overset(..)P CI_(3) = (1)/(2) (5 +3) = 4 =sp^(3)` with one lp of `e^(-')s` it is pyramidal in shape
(b) `SO_(3) = (1)/(2) (6 +0) =3= sp^(2)`
(c ) `CO_(3)^(2-) = (1)/(2) (4 +0 +2) = 3 = sp^(2)`
(d) `NO_(3)^(Theta) = (1)/(2) (5 +0 +1) = 3 = sp^(2)` .
