The complete question is:-
Which of the following molecules has trigonal planar geometry?
(a) BF₃
(b) IF₃
(c) PCl₃
(d) NH₃
Answer:-
BF₃ has a trigonal planar geometry.
- The central atom, i.e. Boron in BF₃ has three bond pairs of electrons and no lone pair of electrons available.
- It undergoes sp² hybridization and has a trigonal planar shape.
- However, PCl₃ and NH₃ have sp³ hybridization and have a pyramidal shape.
- IF₃ has a sp³d hybridization and is 't' shaped.
