Polarity
Can somebody please explain to me why CCl4 is nonpolar even though the dipole moments do not cancel out?
Re: Polarity
The dipole moments do cancel out, the shape is symmetrical, and the surrounding atoms are the same. Their dipoles point in the same direction, so they should cancel out making CCl4 nonpolar.

Re: Polarity
CCl4 has a tetrahedral shape that is symmetrical. Therefore, the bond polarity is canceled out.

Re: Polarity
It is the symmetrical shape of carbon tetrachloride that allows its bond polarity to cancel out.

Re: Polarity
It's a symmetric molecule and has even distributions of electron density; thus, it is nonpolar.

Re: Polarity
For a molecule to be polar, it must possess a non-zero value of dipole moment. In the molecule CCl4, the bond polarity is canceled by the symmetric tetrahedral shape causing the dipole moment to be zero.
