MCQ
Which one of the following does not have a pyramidal shape?
- A$(CH_3)_3N$
- ✓$(SiH_3)_3 N$
- C$P(CH_3)_3$
- D$P(SiH_3)_3$
✓
Answer
Correct option: B.
$(SiH_3)_3 N$
b
In case of $N(SiH_3)_3\, N$ atom is $sp^2$ hybridised, the lone pair is present in $2p$ orbital and it is transferred to empty $d$ orbital of $Si$ forming $d\pi -p\pi $ bond . Hence nitrogen with $sp^2$ hybridization has trigonal planar shape.
