Indeed it is non polar. 

Non polar molecules do not contain a dipole or lacking the ability to form a dipole.

It can also be defined as a nonionic compound; a compound that cannot dissociate into ions in a solution.

Since you are studying biology, we can limit the definitiion of polarity with its ability to be dissolved in a polar subtace for example water.

for example, fats and oils are not soluble in water because they are non polar. Isobutane cannot be dissolved in water therefore it is a non polar substance.


hope this helps :)
