Why CCl4 has always zero dipole?

Expert Answer:

If you see CCl4 molecule, it has four C-Cl bonds. Since, C and Cl both have different electronegativities, the C-Cl bond will be polar.

Now, the CCl4 molecule has all C-Cl bonds i.e. all the bonds are same with same polarity. It is tetrahedral in nature and hence the moleucle is symmetric in nature. So, the indivudual bond polaritites of 4 C-Cl bonds cancel each other and hence the molecule is non- polar.

Therefore, CCl4 will have zero dipole moment.
