MCQ
Which of the following molecules has trigonal planer geometry
- A$I{F_3}$
- B$PC{l_3}$
- C$N{H_3}$
- ✓$B{F_3}$
✓
Answer
Correct option: D.
$B{F_3}$
(d) No. of $e^-$ pair $ = 3 + \frac{1}{2}[3 - 3]=0$
No. of $e^-$ pair $ = 3+0$
No. of atom bonded to the central atom $ = 3$
In case of $3, 3$ geometry is Trigonal planar.
