The polarity of a bond is a deciding factor on whether a molecule is polar or not. However, a molecule experiences dipole interactions only if it is not symmetrical. When a molecule is symmetrical, the bonds of the elements will balance each other having no effect on the molecule.
If a molecule is not symmetrical it usually-
- has a lone pair--> (which offsets the molecules symmetry)
- has more than 2 elements--> (if it has more than two elements then the molecule will not be balanced due to a difference in electronegativity
- Overall it requires the bonds to be polar and the molecule is non-symmetrical in order for a polar molecule
- Remember- Even non-polar molecules can attract other molecules through London dispersion forces--> (the random movement of electrons causing one side of a molecule to be more negative than the other)

∙ 12y agoPolar molecules have stronger intermolecular forces than nonpolar. The more polar a molecule is, the stronger its intermolecular forces will be. Hydrogen has unusually high bond strength when it is bonded with F, O, or N. Ionic bonds have the highest intermolecular forces of all.

Does CH4 have dipole forces?
no
What kind of intermolecular forces exist between octane molecules?
The bonding is covalent and there are also some weaker forces. However, around the ketone group there is polarity.
What is the intermolecular forces of CH3F?
These are polar forces, intermolecular forces of attraction between molecules.
What intermolecular forces are in c5h12?
not an (F,O,N) atom therefore it has no H bond, it has no dipole dipole interactions, plus London forces are weak. Which is why it has a a very low critical temperature.
What is the intermolecular force of Ch2Br2?
Dipole forces and London forces are present as intermolecular forces in these molecules.

Why water is a liquid at room temperature related to its polarity?
Molecules with stronger intermolecular forces will have a greater melting and boiling point than those with weaker intermolecular forces. Due to water's polarity it exhibits dipole-diplole interactions between molecules with the positively charged hydrogen atoms from one water molecule aligning with the negatively charged oxygen atoms. These forces are strong enough to keep water in its liquid state up to 100o C.
Which forces internal or intermolecular must be broken for methyl alcohol to evaporate?
These are intermolecular forces.
What interaction is not a type of intermolecular force?
Intramolecular forces are not intermolecular forces !
What intermolecular forces is the strongest?
hydrogen bonding
What can you say about the relative strength of the intermolecular forces in the two compounds?
The intermolecular forces in acetone are weaker.
