MCQ
In which of the following molecules all the bonds are not equal ?
- ✓$ClF_3$
- B$BF_3$
- C$AlF_3$
- D$NF_3$
✓
Answer
Correct option: A.
$ClF_3$
a
$BF _{3}$ shows trigonal symmetric structure due to sp $^{2}$ hybridization. (Image 1)
$BF _{3}$ shows trigonal symmetric structure due to sp $^{2}$ hybridization. (Image 1)
AlF $_{3}$ shows trigonal symmetric structure due to $sp ^{2}$ hybridization. (Image 2)
$NF _{3}$ shows pyramidal geometry, having equal bonds due to $sp ^{3}$ (Image 3)
ClF $_{3}$ shows trigonal bi-pyramidal due to $\operatorname{dsp}^{3}$ hybridization, in which all bonds are not equal. (Image 4)
Hence, $ClF _{3}$ is the molecule whose bonds are not equal.
Therefore, option A is correct.
