Which of the following is false concerning H 2 O molecules in the hydration shell around nonpolar substances?

So this practice problem asks, which of the following is false concerning the water molecules in the hydration shell around non polar substances? And the answer options are that water molecules in the hydration shell cannot participate in normal hydrogen bonding, they form stronger hydrogen bonds than free water molecules, they're less ordered and have higher entropy than free water molecules, and they have less options for orientations molecules that surrounds the nonpolar substances. So, layer of water molecules that surrounds the nonpolar substances. So it's referring to these water molecules here. And recall from our previous videos that the water molecules in the hydration shell, they actually cannot participate in normal hydrogen bonding. So a here is a true statement, we can scratch it off our list. Also, hydration, water molecules, water molecules in the hydration shell, they move slower and they form fewer but stronger hydrogen bonds than free water molecules. So it's true that they form stronger hydrogen bonds than free water molecules and we can scratch this off. Now c says that they are less ordered and have higher entropy than free water molecules, and this one is actually a false statement. And that's because water molecules in the hydration shell, they have less options for orientations in ordered, not less ordered. And more order, we know, is, correlated with, less entropy. And so it's not higher entropy, it's less entropy and more order. And so because this is incorrect and false as written, this is our answer option that we're selecting. And so we can indicate that C is the correct answer here and I'll see you guys in our next video.

Verified step by step guidance

Understand the concept of a hydration shell: When nonpolar substances are introduced into water, water molecules form a structured shell around them, known as the hydration shell.

Recall the nature of hydrogen bonding: Water molecules can form hydrogen bonds with each other, which are relatively strong interactions that contribute to water's unique properties.

Consider the behavior of water molecules in the hydration shell: Around nonpolar substances, water molecules are more ordered because they cannot form hydrogen bonds with the nonpolar substance, leading to a structured arrangement.

Analyze the entropy of water molecules: In the hydration shell, water molecules have fewer options for orientation and movement compared to free water molecules, resulting in lower entropy.

Evaluate the statements: The statement 'Less ordered & higher entropy than free H2O' is false because water molecules in the hydration shell are more ordered and have lower entropy compared to free water molecules.
