Final answer:
CH3OH (methanol) is the compound among the options that exhibits hydrogen bonding due to the presence of a hydroxyl (-OH) group.
Step-by-step explanation:
The compound that has hydrogen bonding among the given options is CH3OH (methanol). In order to have hydrogen bonding, a molecule must contain hydrogen attached to a highly electronegative atom like oxygen, nitrogen, or fluorine, which can act as a hydrogen bond donor. CH3OH meets this criterion because it has a hydroxyl (-OH) group where hydrogen is directly bonded to oxygen, a highly electronegative atom. This allows it to participate in hydrogen bonding due to the oxygen's lone pairs of electrons.
Other compounds, such as (CH3)3N (trimethylamine), lack a hydrogen atom necessary for the bonding; Br2 (bromine), CH3CH3 (ethane), and HBr (hydrogen bromide) do not contain the OH, NH, or FH groups necessary for hydrogen bonding.
