In which of the following molecules all the atoms lie in one plane ? .

A

`overset(..)NH_(3)`

B

`PF_(5)`

C

`BF_(3)`

D

`XeF_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C, D
`overset(..)NH_(3)` is `sp^(3)` hybridised and pyramidal in shape
(b) `PF_(5)` is `sp^(3)` dhybridised and has Tbp geometry
(c ) `BF_(3)` is `sp^(2)` hybridised and is planar triangular
(d) `:overset(..)Xe F_(4)` is `sp^(3) d^(2)` hybridised and with two lp of `e^(-')s` it has square planar shape So in (c ) and (d) all atoms line in one plane .
