Is the caffeine molecule polar or nonpolar?

Solution

Yes, caffeine is a polar molecule.

The $$ \textbf{Oxygen} $$ and $$ \textbf{Nitrogen} $$ molecules have a stronger polarity than $$ \textbf{Carbon} $$. allowing them to slightly pull the electrons towards them in their covalent bond. This will give those atoms a slightly negative charge while giving the $$ \textbf{Carbon} $$ a positive charge. This is the exact definition of polarity itself.

A non-atomic way of figuring it out is by water solubility or oil solubility. Water is polar, oil is non-polar. Polar substances dissolve in each and vice verse. Caffeine is water-soluble.
