MCQ
The incorrect geometry is represented by
- ✓$NF_3-$ trigonal planar
- B$BF_3-$ trigonal planar
- C$AsF_5-$ trigonal bipyramidal
- D$H_2O-$ bent
✓
Answer
Correct option: A.
$NF_3-$ trigonal planar
a
$NF_3$ has trigonal pyramidal geometry. $N$ atom has one lone pair and three bond pairs of electrons. The electron pair geometry is tetrahedral and molecular geometry is trigonal pyramidal . The bond angles are lower than tetrahedral bond angles due to lone pair - lone pair and lone pair - bond pair repulsions. $N$ atom is $sp^3$ hybridised
