How does the boiling point affect polarity?

Answer 1

I think the question should ask #"how does polarity affect boiling point?"#

Polar interactions between molecules in the condensed phase are caused by molecular polarity, and these interactions have the potential to form an intermolecular force that should raise the boiling point.

Now this might not be the best example I could draw (and I would welcome suggestions of more apposite molecules), but consider the normal boiling points of chloroform, #61.2# #""^@C# versus that of carbon tetrachloride, #76.2# #""^@C#. The heavier molecule should be and is MORE involatile...but nevertheless, because chloroform has a molecular dipole moment, its boiling is elevated with respect to non-polar carbon tet…

The boiling point of a substance is influenced by its polarity. Generally, polar molecules have higher boiling points than nonpolar molecules because polar molecules experience stronger intermolecular forces such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces, which require more energy to overcome and reach the boiling point.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
