Silane is more reactive than `CH_(4)` towards `Nu^(-)` substitution due to :

Options

A. larger size of Si compared to C which facilitating the attack by nucleophile
B. Polarity of `Si-H` bonds is opposite to that of `C-H` bond
C. Availability of vacant 3d orbitals in case to form the reaction intermediate easily for nucleophilic attack
D. `Si-H` bond energy is lower than that of `C-H` bonds

Answer

A, B, C, D

Explanation

`overset(delta+)(Si)-overset(delta-)(H)` `overset(delta-)(c)-overset(delta+)(H)`
