Non polar
The given compound is carbon tetrachloride.(CCl4). Each C-Cl bond is polar as Cl is more electronegative than C. But the shape of CCl4 is tetrahedral , the bond polarity is cancelled due to symmetric tetrahedral shape. Hence the net dipole moment is zero leading to non polar nature.

1st attempt M See Periodic Table Two liquids - one polar, one nonpolar - have the same molar mass. Which one has the higher boiling point? Choose one: A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass.

Decide whether each molecule or polyatomic ion is polar or nonpolar, If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table.

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
