Final answer:
The molecule that can exhibit hydrogen bonding is HOCH2CH2OH.
Step-by-step explanation:
The molecule that can exhibit hydrogen bonding is:
B. HOCH2CH2OH
In this molecule, there are hydrogen atoms attached to an oxygen atom, which makes it a hydrogen bond donor. Additionally, the oxygen atom has two lone pairs of electrons, making it a hydrogen bond acceptor. Therefore, this molecule can form hydrogen bonds by acting as both a donor and an acceptor.
