Electron Configuration: Which Structure Shows The Correct Electron Arrangement In Ccl4
The electron configuration of carbon is 1s 22s 22p 2, while that of chlorine is 1s 22s 22p 63s 23p 5. In the formation of CCl 4, carbon contributes its four valence electrons (2s 22p 2), and each chlorine atom contributes one valence electron (3p 1). These valence electrons participate in covalent bond formation, resulting in a total of eight bonding electrons.
Molecular Geometry
CCl 4has a tetrahedral molecular geometry. The carbon atom is at the center of the tetrahedron, with the four chlorine atoms occupying the corners. The bond angles between the carbon-chlorine bonds are 109.5°, which is consistent with the tetrahedral geometry.
Lewis Structure
The Lewis structure of CCl 4shows the arrangement of electrons around the carbon atom. The carbon atom is represented by the letter C, and the chlorine atoms are represented by the letter Cl. The four chlorine atoms are bonded to the carbon atom by single covalent bonds.
The Lewis structure of CCl 4is:
Hybrid Orbitals
The carbon atom in CCl 4undergoes hybridization of its valence orbitals. The 2s and three 2p orbitals hybridize to form four equivalent sp 3hybrid orbitals. These hybrid orbitals have a tetrahedral shape and are directed towards the corners of a tetrahedron.
The sp 3hybrid orbitals overlap with the p orbitals of the chlorine atoms, forming four covalent bonds.
Molecular Polarity
CCl 4is a nonpolar molecule. This is because the four C-Cl bonds are polar, but the polarities cancel each other out due to the tetrahedral symmetry of the molecule. The individual C-Cl bonds have a dipole moment pointing from the carbon atom to the chlorine atom, but the vector sum of these dipole moments is zero.
Applications
CCl 4has a wide range of applications, including:
- As a solvent for nonpolar substances, such as oils and greases.
- As a cleaning agent for metal surfaces.
- As a fire extinguisher.
