Question

Consider the following list of gases:

Answer 1

Explanation:

Molecules which are either polar in nature or contain a polar covalent bond are able to dissolve in water. This is because like dissolves like.

For example, $SO_{3}$ is a polar covalent compound and when it is dissolved in water then its reaction is as follows.

       $SO_{3} + H_{2}O \rightarrow H_{2}SO_{4}$

This shows that a chemical reaction will take place when $SO_{3}$ is dissolved in water.

Also, HI is a polar covalent compound and it will readily dissolve in water as hydrogen iodide (HI) is a polar covalent molecule.

On the other hand, $H_{2}$, $SF_{6}$, and $C_{2}H_{4}$ does not dissolve in water as all of these are non-polar covalent compounds.

Thus, we can conclude that the gas most likely to dissolve in water as a result of chemical reaction is $SO_{3}$ and the gas most likely to dissolve in water because of strong intermolecular interactions is HI.
