Why is pyramidal but is planar ? |
|
Answer» re is UR answer.....In CASE of N ( CH3 )3 , GEOMETRY is pyramidal and in case of N ( SiH3 )3 , geometry is planar In Trimethyl Amines,N ATOM is Sp3 hybridized which results in pyramidal geometry. There is no Pi bonding bcz C has no low- lying- orbital..In Trisilyl Amines N atom is Sp2 hybridized which results in planar geometry. There is P!! - D!! bonding bcz Si has vacant D - orbital.. Filled 2P orbital of N overlaps with vacant 3d orbital of Si to from p!! - D!! BOND.. thanks...mark it as brainliest i request u plz |
