Question

Noble gases are strongly soluble in water, owing to:
A. dipole-dipole interactions
B. dipole-induced dipole interaction
C. hydrogen bonding
D. induced dipole-instantaneous dipole interactions

Answer 1

Hint: Noble gases, as their name implies, are inert gases that do not react with anything. Noble gases include helium, neon, argon, krypton, and xenon. Radon is a radioactive noble gas. These gases contain a full octet outer layer, making them extremely stable and inert.

Complete Step by Step Solution:
We must understand that noble gases are non-polar elements that can dissolve, but only to a limited extent. We must first examine the pattern in atom size as we progress down the periodic table's groups. As we progress through the group, the atomic size grows larger.
A dipole-induced dipole force occurs when a polar molecule causes a dipole in a nonpolar atom or molecule by altering the electron configuration in the nonpolar species. The presence of a polar molecule causes the electron arrangement of the other molecule to be polarised, or distorted. The second molecule obtains partial positive and negative charge areas as a result of this distortion and hence becomes polar. This partially charged state behaves like a permanent polar molecule, resulting in a regular dipole interaction with the polar molecule that caused it.

It is important to note that solubility refers to a substance's ability to dissociate in water and is determined by dipole-dipole interaction. Because of dipole-induced dipole interaction, noble gases are soluble in water. Dipole-dipole forces are the attractive interactions between the positive ends of one polar molecule and the negative ends of another.
As a result, the correct answer is option B dipole-induced dipole interaction.

Additional Information: As the size of the dipole reduces, the dipole-dipole interaction decreases and the dipole-dipole interaction decreases, the dipole-dipole interaction decreases, and the dipole-dipole interaction drops We can conclude that Helium is the least soluble noble gas in water due to its tiny atomic size and thus stronger dipole-dipole interactions, while Radon is the most soluble noble gas.

Note: Noble gases are employed in situations where a stable element is required to provide a safe and consistent atmosphere. Noble gases are abundant in the outer shell of valence electrons, making them less likely to participate in chemical reactions and so inert. Polarizability, or the tendency to polarise, is another word for these noble gases' solubility.
