MCQ
The geometry and the type of hybrid orbital present about the central atom in $B{F_3}$ is
- ALinear, $sp$
- ✓Trigonal planar, $s{p^2}$
- CTetrahedral, $s{p^3}$
- DPyramidal, $s{p^3}$
✓
Answer
Correct option: B.
Trigonal planar, $s{p^2}$
b
In $BF _3, B$ is $sp ^2$-hybridised.
In $BF _3, B$ is $sp ^2$-hybridised.
These three $sp ^2$-hybrid orbitals are attached to each other trigonally with an angle of $120^{\circ}$ and they are overlapped with three $p$ - orbitals of three $F$ atoms on their axes. Hence, the geometry of $BF$, molecule is trigonal planar.
