Question

Distinguish between polar and non polar molecules

Answer 1

First off, if the molecule is symmetrical, it is probably non-polar. An example is CO2, CH4, or SeF5.

An idea of if it is polar, unequal sharing of electrons. H20. The shape is actually a tetrahedral. The same structure at CH4. Though in the place of two H's, there are 4 e- . This makes the molecule not symmetrical.

Think of H2O as this. The side where the H's are is slightly more positive. The side where the two pairs of electrons are, the molecule is slightly negative. The molecule overall is a neutral charge, but different portions of the molecule have slight variations in charge.

In the molecule C2H2Cl2, there are three different structures. One with both Cl's on one carbon, one with both Cl's are either top and bottom, or both Cl's at diagonals. When they are at diagonals the molecule is non-polar. In both other cases it is polar.

Answer 2

hope it helps

Answer 3

strong copy paste, but ty anyway

Answer 4

Poplar is they have dipole moment, non polar is when molecular doesn't have dipole moment. . Dipole moment = 0
