D) Acetone and Acetonitrile


Both acetone and acetonitrile contain a polar bond. Both molecules have what is called a Hydrogen Bond Acceptor, but neither of them have a Hydrogen Bond Donor.

So these two molecules will interact with each other through their polar regions (dipole regions - forming a Dipole-Dipole interaction).

Acetone's polar bond: C=O
Acetonitrile's polar bond: C=N (except it is a triple bond - I don't know how to make a triple bond on here).
