Question

question 20 1 pts which of the following molecules has hydrogen bonding as its only intermolecular force? bh3 none, all of the choices exhibit dispersion forces h2o nh3 hoch2ch2oh

Explanation:

All molecules have London - dispersion forces (also known as van der Waals forces). London - dispersion forces are the weakest intermolecular forces and are present in all molecules, whether polar or non - polar. $BH_3$ is a non - polar molecule and has only dispersion forces. $H_2O$, $NH_3$, and $HOCH_2CH_2OH$ have hydrogen bonding, but they also have dispersion forces due to the presence of electrons in their molecules.

Answer:

B. None, all of the choices exhibit dispersion forces
