Chemical Bonding And Molecular Structure Question 161
Question: Which of the following molecules has trigonal planer geometry [CBSE PMT 2005]
Options:
A) $ IF_3 $
B) $ PCl_3 $
C) $ NH_3 $
D) $ BF_3 $
Show Answer
Answer:
Correct Answer: D
Solution:
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.
