Predict whether the following molecules are isostructural or not Justify your answer
`N(Me)_(3)` and `N(SiH_(3))_(3)` .

Text Solution

Verified by Experts

They are not isostructural `N(Me)_(3)` is pyramidal in shape due to `sp^(3)` hybridisation
`N(SiH_(3))_(3)` is trigonal planar Nitrogen atom shows `sp^(2)` hybridisation The structure is stabilised by the donation of lone pair of electrons from nitrogne into vacant d-orbitals of silicon forming `(p pi-d pi)` back bonding .
