CH2Cl2 is a polar molecule due to its tetrahedral geometrical shape and difference between the electronegativity of Carbon, Hydrogen and Chlorine atoms.

This develops a dipole moment across C-Cl and C-H bonds and the entire molecule results in a net 1. This results in a polar molecule with a large dipole moment. In the case of CCl2O, the two electronegative chlorine atoms on the opposite side of the molecule to the oxygen atom, will tend to counter the pull of electrons to the oxygen. This will lead to a smaller overall dipole moment in the molecule.

The SiCl4 S i C l 4 is a non-polar molecule. Polarity in molecules arises from the separation of partial charges due to the electronegativity…. Answer: SiCl4 Silicon Tetrachloride is a nonpolar molecule because all of the four chlorine molecules are equally spaced around the central silicon atom in a tetrahedral structure.

In this scenario the chlorine receives a partial negative charge and the silicon gets a partial positive charge. Dipole -dipole interactions occur when the partial charges formed within one molecule are attracted to an opposite partial charge in a nearby molecule.

Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule. The four chlorine atoms are positioned symmetrically at the four corners of a tetrahedron, and a single bond joins each of them to the carbon atom in the center of the molecule.

As a result, CCl4 has no net positive or negative dipole moment. Due to the difference between the electronegativity of fluorine and xenon atom, the molecule of XeF2 ensures non zero dipole moment originating in the direction of fluorine.
