Multiple Choice
A hydrogen bond __________.
A
is one in which two hydrogen atoms bond to each other
B
is one in which hydrogen is strongly attracted to a positively charged atom
C
is a function of hydrophobic interactions
D
is a weak chemical bond
Verified step by step guidance
1
Understand that a hydrogen bond is a type of weak chemical bond that occurs when a hydrogen atom covalently bonded to a more electronegative atom, such as oxygen or nitrogen, experiences an attraction to another electronegative atom nearby.
Recognize that hydrogen bonds are not formed between two hydrogen atoms. Instead, they involve a hydrogen atom that is already part of a polar covalent bond.
Identify that hydrogen bonds are not primarily driven by hydrophobic interactions, which involve the tendency of nonpolar substances to aggregate in aqueous solutions to minimize their exposure to water.
Note that hydrogen bonds are characterized by the attraction between a partially positive hydrogen atom and a partially negative atom, often oxygen or nitrogen, in another molecule or within the same molecule.
Conclude that the correct description of a hydrogen bond is that it is a weak chemical bond, which plays a crucial role in the structure and properties of water, proteins, and nucleic acids.
