Which of the following molecules has trigonal planar geometry ?

A

`BF_(3)`

B

`NH_(3)`

C

`PCl_(3)`

D

`IF_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`BF_(3)` is `sp^(2)` hybridised. So, it is trigonal planar. `NH_(3) and PCI_(3)` have `sp^(2)` hybridisation, hence have trigonal pyramidal shape. `IF_(3)` has `sp^(3)` d hydridisation and has T-shape.
