The molecule CCl4 has 32 total valence electrons, the shape is Tetrahedral and it is Norcol polar or nonpolar) the molecule contains double bonds
The Correct Answer and Explanation is :
The correct information is as follows:
- Molecule: CCl₄ (Carbon Tetrachloride)
- Valence Electrons: 32 (4 from Carbon + 7×4 from Chlorine atoms)
- Shape: Tetrahedral
- Polarity: Nonpolar
- Double Bonds: No (CCl₄ contains single bonds between Carbon and Chlorine).
Explanation:
Valence Electrons
Carbon has 4 valence electrons, and each chlorine atom contributes 7 valence electrons. Since there are 4 chlorine atoms, the total is:
[ 4 + (7 \times 4) = 32 \, \text{valence electrons.} ]
Bonding and Shape
Carbon forms four single covalent bonds with four chlorine atoms. Chlorine is highly electronegative, so each bond is polar covalent. The geometry of the molecule is determined by the VSEPR theory (Valence Shell Electron Pair Repulsion). Since there are four bonding pairs and no lone pairs on the central carbon, the shape of the molecule is tetrahedral, with bond angles of approximately (109.5^\circ).
Polarity
Although the individual C-Cl bonds are polar due to the difference in electronegativity between carbon and chlorine, the molecule is nonpolar overall. This is because the tetrahedral shape causes the dipoles of the polar bonds to cancel out symmetrically, resulting in no net dipole moment.
Double Bonds
CCl₄ does not contain any double bonds. Each chlorine atom is bonded to the central carbon via a single covalent bond. Chlorine cannot form double bonds in this molecule because it has a stable configuration with a single bond and its octet is already complete.
In summary, CCl₄ is a nonpolar molecule with 32 valence electrons, a tetrahedral shape, and single covalent bonds between carbon and chlorine atoms. Its symmetry ensures that the molecule is nonpolar despite containing polar bonds.
