Okay, everyone. Cohesive forces in liquid water occur when what? Okay. So remember that cohesion or cohesive forces is one of many emergent properties of water that we've been learning about. And remember that cohesive forces or cohesion is when water molecules stick together. So when do water molecules stick together? Remember that this is going to occur when water molecules are hydrogen bonding. And just in case if you've forgotten, the hydrogen bond occurs between the partially negative then, voila, they are stuck together. They have cohesive forces due to hydrogen bonding, and that is the reason for cohesion. And if you look at our answer choices, the only answer that lays this out perfectly is answer choice a. Okay, everyone. Let's move on to our next video.

Verified step by step guidance

Understand the concept of hydrogen bonding: Hydrogen bonds are weak interactions that occur between a hydrogen atom covalently bonded to an electronegative atom (like oxygen) and another electronegative atom.

Identify the structure of a water molecule: Water (H2O) consists of two hydrogen atoms and one oxygen atom. The oxygen atom is more electronegative, creating a partial negative charge, while the hydrogen atoms have a partial positive charge.

Recognize the nature of cohesive forces: Cohesive forces refer to the attraction between molecules of the same substance. In water, these forces are primarily due to hydrogen bonding.

Determine the correct hydrogen bonding interaction: In liquid water, the hydrogen atoms of one water molecule form hydrogen bonds with the oxygen atoms of adjacent water molecules, not with other hydrogen atoms.

Evaluate the given options: The correct answer is that the hydrogen atoms on molecules of H2O hydrogen bond to oxygen atoms on adjacent molecules of H2O, which aligns with the nature of hydrogen bonding and cohesive forces in water.
