N(CH_3)_3 is pyramidal but N (SiH_3)_3 is planar-explain. |
| Answer» Solution :Because of d -orbital RESONANCE, the N-atom in `N(SiH_3)_3` MOLECULE is `sp^2` - hybridised and therefore, the molecule is planar. No such d -orbital resonance OCCURS in `N(CH_3)_3` and the central N-atom is `sp^3` -hybridised. For this reason, this molecule is pyramidal. | |
