Chapter 9 - Covalent Bonding: Orbitals - Exercises: 18

Answer

$CCl_4$ consists of 4 chlorine atoms single-bonded to a central carbon atom. The molecular geometry is tetrahedral, and the bond angles are $109.5^{\circ}$.

Work Step by Step

$CCl_4$ has a tetrahedral electron arrangement due to the carbon atom's $sp^3$ hybridization. Since all 4 of the sp3 hybrid orbitals hold bonding pairs, there are no lone pairs about the carbon atom. Therefore, the molecular structure is tetrahedral. Since all 4 of the carbon atom's hybrid orbitals hold identical C-Cl bonds, the bond angles are identical and all $109.5^{\circ}$.
