Molecules that contain two polar bonds are . a. sometimes ionic . b. always non polar c. always polar d. sometimes polar

D.sometimes polar

Explanation:

A molecule that has two polar bonds can be polar or non polar, it all depends on the bonds that form it, a polar bond is what happen whe you mix two elements and the distribution of electrons is uneven, imagine a polar bond as being "Uneven and even numbers" Polar is uneven and non polar is even, if you add up two even numbers it would always give as a result an even number, with polar and non polar, two polar bond will always result in a polar bond, but two non polar bonds would sometimes create non polar bonds or polar bonds, depending on the elements being bonded.
