Detailed explanation-1: -Answer: CCl4, a carbon tetrachloride, is stated to be nonpolar. The reason for this is that all four bonds in carbon tetrachloride are symmetrical and also, and they are extended in all directions.

Detailed explanation-2: -Now, if we look, we see that there is a line of symmetry in both of these, and that line of symmetry is going to cause these dipole moments to cancel out. So our di pole moments are going to cancel out due to symmetry, and that’s going to make them both non polar.

Detailed explanation-3: -Carbon tetrachloride is nonpolar. Why is carbon tetrachloride nonpolar? It is nonpolar because the dipole moments of the molecule are evenly spaced around the central carbon atom. This means that their individual effects are canceled out, and the molecule is neutral.

Detailed explanation-4: -Why CCl4 is non-polar but CHCl3 is polar? Give reasons. CCl4 is nonpolar because the bond polarity gets canceled with each other due to the symmetrical geometrical structure of its molecule. CHCl3 is polar due to its tetrahedral molecular structure and difference between the electronegativity of C, H and, CL.
