Draw the Lewis structure of Carbon Tetrachloride,

........Cl
..........|
Cl --- C --- Cl
..........|
........Cl
http://www.chemguide.co.uk/atoms/bonding/ccl4.GIF
{The top Cl is sticking up where as the bottom 3 Cl form a tripod like base opening down....overall, it is a tetrahedral molecule}

The carbon atom forms 4 polar covalent bonds with 4 separate Chlorine atoms. Each of the Cl atoms have a slight negative charge while the C atom has a slight positive charge However, all these bonds are positioned in such a way so that they cancel each other out.

The result is a non-polar molecule.

There are two criteria for a molecule to be polar: it must have polar bonds and the polar bonds cannot cancel out due to symmetry.

Although the CCl4 bond is a polar bond due to the symmetry (Td) of the molecule the polar bonds all cancel out leaving a non-polar molecule.

That is because the dipoles cancel each other. The resultant is a 0 dipole molecule even though all 4 bonds are polar.

CCl has a polar covalant bond but because this molecule has sp3 hybrid and because of it's geometrical position of the atoms
it makes molecule to nuetrilize this polar covalant bond and at last the entire molecule is non-polar! Organic Chemistry " Morisson Boid "

ccl4 is non polar because it has no net dipole moment .
it being a symmetrical molecule ( trigonal planar geometry) all the bond moments cancel each other

even though all four bonds are polar, they are equally spaced, so the pull from the chlorines is cancelled out. think of it sort of like four equally-matched people in a four-way tug-of-war.

yes the dipoles cancel each other out.

it has 2 names it extremely is declared as carbon tetrachloride or tetrachloro-methane,that compound is shaped as a consequence of oblique halogenation of CH4 as: CH4 + Cl2 -----> CH3-Cl + HCl in oblique solar mild then CH3-Cl + Cl2 -----> CH2-Cl2 + HCl then CH2-Cl2 + Cl2 ----> CH-Cl3 + HCl lastly CH-Cl3 + Cl2 -----> CCl4 + HCl or you may only write CH4 + Cl2 ----> CCl4 + 4 HCl yet submit to in innovations that occurs in basic terms in oblique image voltaic,together as in direct image voltaic CH4 + Cl2 ----> C + HCl i be conscious of i wrote too plenty,sorry xD
