Verified step by step guidance
1
Identify the functional groups in CH3CH2NHCH2OH: it contains an amine group (NH) and an alcohol group (OH).
Understand that hydrogen bonds can form between hydrogen atoms attached to electronegative atoms (like N or O) and lone pairs on electronegative atoms in water.
Recognize that the NH group can form a hydrogen bond with water because the hydrogen attached to nitrogen can interact with the lone pair on the oxygen of a water molecule.
Note that the OH group can also form a hydrogen bond with water, as the hydrogen attached to oxygen can interact with the lone pair on the oxygen of a water molecule.
Consider that the lone pairs on the nitrogen and oxygen in CH3CH2NHCH2OH can also accept hydrogen bonds from the hydrogen atoms in water molecules, allowing for additional hydrogen bonding interactions.
