It can basically bond with this partially positive charge. Now the other type of intermolecular bond that you have to be familiar with in your study of biochemistry are the London Dispersion forces. Now in biochemistry sometimes the London Dispersion forces are also called Van der Valve forces. So in biochemistry, if somebody ever tells you or refers to the Vanderbilts forces, they are probably referring to the London dispersion forces. The reason this is technically incorrect is because actually, all intermolecular bonds are technically vanderball's forces. But sometimes in biochemistry, they use these two terms interchangeably.
