When do hydrogen bonds occur?
A
When a molecule with partial charges contacts a molecule without partial charges
B
When a molecule with a low molecular weight is bonded to a molecule with a high molecular weight
C
When two atoms achieve stable electron configurations by sharing electrons with each other
D
When partial opposite charges on molecules come close enough to attract each other
Verified step by step guidance1
Understand that hydrogen bonds are a type of weak chemical bond that occurs between molecules.
Recognize that hydrogen bonds form when there is an attraction between a hydrogen atom, which is covalently bonded to a more electronegative atom, and another electronegative atom with a lone pair of electrons.
Identify that the key feature of hydrogen bonds is the presence of partial positive and partial negative charges, often involving atoms like oxygen, nitrogen, or fluorine.
Note that hydrogen bonds occur when these partial opposite charges on different molecules come close enough to attract each other, leading to the formation of a hydrogen bond.
Remember that hydrogen bonds are crucial in many biological processes, such as the structure of DNA and the properties of water.
