Which of the following statements is/are false ?

Options

A. `Nme_(3) and N(SiH_(3))_(3)` are not isostructural
B. Methyl isocyanate `(CH_(3)-N=C=O)` is bent but silyl isocyanate `(SiH_(3)-N=C=O)` is linear
C. In trisilyl amine `[(SiH_(3))_(3)N]` all N-Si bond lengths are identical but shorter than the expected N-Si bond length
D. None

Answer

D

Explanation

(i) `underset("(planar)")underset("Back bonding is posible")(N(SiH_(3))_(3))" "underset("(pyramidal)")underset("Back bonding is not possible")(N(Me)_(3))`
(ii) `H_(3)C-N=C=O` back bonding not possible (bent
`H_(3)Si-N=C=O` back bonding present so shape is linear
(iii)
