The geometry of `SiCl_(4)` is

Options

A. Tetrahedral
B. Square planar
C. Octahedral
D. Planar triangular

Answer

To determine the geometry of SiCl₄ (silicon tetrachloride), we can follow these steps:

### Step 1: Identify the central atom and its bonds
- The central atom in SiCl₄ is silicon (Si).
- Silicon is bonded to four chlorine (Cl) atoms.

### Step 2: Count the number of sigma bonds
- Each Si-Cl bond is a sigma bond.
- In SiCl₄, there are 4 Si-Cl bonds, which means there are 4 sigma bonds.

### Step 3: Determine the hybridization
- The hybridization can be determined based on the number of sigma bonds.
- For 4 sigma bonds, the hybridization is sp³.

### Step 4: Determine the molecular geometry
- The geometry associated with sp³ hybridization is tetrahedral.
- Therefore, the molecular shape of SiCl₄ is tetrahedral.

### Summary of the Geometry
- The geometry of SiCl₄ is tetrahedral.
