Question

The structure and hybridization of $Si(C{H}_3{)}_4$ is:

• A. Bent, sp
• B. Trignonal, $s{p}^2$
• C. Octahedral, $s{p}^3{d}^2$
• D. Tetrahedral, $s{p}^3$

Answer 1

The correct option is D

Tetrahedral, $s{p}^3$

TMS or tetramethylsilane has a tetrahedral framework and according to VSEPR theory, an $s{p}^3$-hybrid central atom.
