The structure and hybridisation of $Si(CH_3)_4$ is

Question

What is the chemical formula of glycerol?

Answer 1

To determine the structure and hybridization of $Si(CH_3)_4$, we will analyze the bonding and electron arrangement around the silicon atom.

Valency and Bonds:
- Silicon (Si) belongs to group 14 of the periodic table and has four valence electrons.
- In $Si(CH_3)_4$, each methyl group $(CH_3)$ is bonded to the central Si atom through a single covalent bond.
- This implies that there are four sigma bonds around silicon.
Hybridization:
- With four sigma bonds around, the silicon atom utilizes its four sp³ hybrid orbitals.
Geometry:
- The sp³ hybridization of silicon results in a tetrahedral geometry.
- In a tetrahedral geometry, the bond angles are approximately 109.5°.
Conclusion:
- Therefore, the molecule $Si(CH_3)_4$ has a tetrahedral shape and sp³ hybridization.

Thus, the correct answer is $tetrahedral, sp^3$.
