Options

A. tetrahedral
B. triangular
C. linear
D. octahedral

Answer

To determine the geometry of carbon tetrachloride (CCl₄), we can follow these steps:

### Step 1: Identify the central atom
In CCl₄, the central atom is carbon (C).

### Step 2: Determine the number of valence electrons
Carbon has 4 valence electrons, and each chlorine (Cl) atom has 7 valence electrons. Since there are four chlorine atoms, we can calculate the total number of valence electrons in CCl₄:
- Valence electrons from carbon: 4
- Valence electrons from 4 chlorine atoms: 4 × 7 = 28
- Total valence electrons = 4 + 28 = 32

### Step 3: Draw the Lewis structure
In the Lewis structure of CCl₄, the carbon atom is in the center, and it forms single bonds with each of the four chlorine atoms. This uses up all 32 valence electrons (4 bonds × 2 electrons per bond = 8 electrons used).

### Step 4: Determine the steric number
The steric number is the number of atoms bonded to the central atom plus the number of lone pairs on the central atom. In CCl₄:
- Number of bonded atoms (Cl) = 4
- Number of lone pairs on carbon = 0
- Steric number = 4 + 0 = 4

### Step 5: Predict the molecular geometry
With a steric number of 4 and no lone pairs, the molecular geometry of CCl₄ is tetrahedral.

### Final Answer
The geometry of CCl₄ is tetrahedral.
