Verified step by step guidance1
Identify the molecular structure of CCl_4 (carbon tetrachloride). It consists of one carbon atom bonded to four chlorine atoms in a tetrahedral geometry.
Recall that a polar bond occurs when there is a difference in electronegativity between the two atoms involved in the bond.
Determine the electronegativity values of carbon and chlorine. Carbon has an electronegativity of about 2.55, and chlorine has an electronegativity of about 3.16.
Since chlorine is more electronegative than carbon, each C–Cl bond is polar due to the difference in electronegativity.
Count the number of C–Cl bonds in the molecule. There are four such bonds, so there are four polar bonds in CCl_4.
