The shapes of `PCI_(4)^(o+),PCI_(4)^(Θ)` and `AsCI_(5)` and are respectively .

A

Squar planar, tetrahedral and see-saw

B

Tetrahedral,see-saw and trigonal bipyramidal

C

Tetrahedarl ,square planar and pentagonal bipyramidal

D

Trigonal bipyramidal, tetrahedral and square pyramidal

Text Solution

Verified by Experts

The correct Answer is:
B
Hybridisation
`PCI_(4)^(o+) implies (1)/(2) (5 +4 +1) implies 4 = sp^(3),` no lp of `e^(-')s` hence `TH`
`PCI_(4)^(Theta) implies (1)/(2) (5 +5) 5 =sp^(3)` d, one lp of `e^(-')s` hence see -saw
`AsCI_(5) implies (1)/(2) (5 +5) 5 =sp^(3)` d, no lp of `e^(-')s` hence Tbp .
