### Polar

How do you know if a molecule is polar or not so you can state whether it is a dipole-dipole or london dispersion?

### Re: Polar

If one "side" of the molecule has a greater electronegativity, which means one side will attract the electrons much more than the other, then it'll be polar

### Re: Polar

You can tell if it is polar by electronegativity. If an atom has more electronegativity than the other, it will be partially negative, pulling electrons towards it, leaving the other atom partially positive

### Re: Polar

Polar forces usually occur between those with a difference of electronegativity while dispersion forces occur between all molecules. For example, carbon dioxide has polar forces while chloride gas has dispersion forces.

PERIODIC TABLE TRENDS. MORE ELECTRONEGATIVITY DIFFERENCE SIGNIFIES MORE POLAR MOLECULE...

### Re: Polar

Non-polar would show charge distribution as symmetric while polar molecules would show an asymmetric charge distribution. You can also use electronegativity to determine this.

### Re: Polar

A difference in electronegativity between the atoms results in a polar molecule.

### Re: Polar

Polarity depends on electronegativity. The difference of electronegativty between the two atoms signifies whether they will have a positive or negative partial charge.

A dipole-dipole interaction between molecules alludes that the molecule is polar while london dispersion forces alludes to the molecular interactions being non polar. An interaction, in all cases, is considered covalently polar if the differenece in electronegativity of the 2 atoms is greater than 0.5 and less than 1.5.
