The correct answer is a nonpolar molecule with polar bonds.
Carbon tetrachloride (CCl4) consists of one carbon atom bonded to four chlorine atoms. Each of the carbon-chlorine (C-Cl) bonds is polar due to the difference in electronegativity between carbon and chlorine. Chlorine is more electronegative than carbon, which results in a partial negative charge on the chlorine atoms and a partial positive charge on the carbon atom.
However, the geometry of the CCl4 molecule is tetrahedral and symmetric, meaning that the individual bond dipoles cancel each other out. This symmetrical arrangement allows the molecule to have no net dipole moment, resulting in CCl4 being classified as a nonpolar molecule overall.
In summary, while CCl4 contains polar bonds (the C-Cl bonds), its symmetrical shape leads to it being a nonpolar molecule as a whole.
