Question:
(SiH$_3$)$_3$N is
(SiH$_3$)$_3$N is
Show Hint
Delocalization can flatten pyramidal geometry.
Updated On: Apr 23, 2026
- planar
- pyramidal
- octahedral
- tetrahedral
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Delocalization of lone pair reduces pyramidal nature
Step 1: N has lone pair.
Step 2: Lone pair gets delocalized into Si orbitals.
Step 3: This reduces repulsion → structure becomes planar.
Conclusion:
Shape = Planar
