How do we order them considering their solubility?
CH4 , NH3 , Cl2 , CO2
Ammonia make H bonds with water,which makes it the most soluble.
CH4 only have Vander Valls forces.
I've heard Cl2 disdolves in considerable amounts in water.
So how do we order them?
Cl2
I would look on Google, especially one with a link to Wikipedia, and those almost always list the solubility in a chart on the right hand side.
I would list them as
NH3>Cl2>CO2>CH4 but confirm that Cl2 and CO2 are in the correct order there.
Actually they are the ones i need a comfirmation.Thank you!
To order the given substances based on their solubility, we need to consider the types of intermolecular forces each substance exhibits. The general rule is that substances with stronger intermolecular forces tend to be more soluble in a given solvent.
Let's analyze each substance:
1. CH4 (methane): Methane only exhibits weak van der Waals forces. Although it can dissolve in some extent in nonpolar solvents like oil or hexane, it is relatively insoluble in water due to the weak intermolecular forces. Therefore, we can assume that CH4 has the lowest solubility among the given substances.
2. NH3 (ammonia): Ammonia is a polar compound that can form hydrogen bonds with water molecules. Hydrogen bonding is a strong intermolecular force, resulting in good solubility in water. Therefore, NH3 is more soluble than CH4.
3. Cl2 (chlorine): Chlorine is a nonpolar molecule and does not form hydrogen bonds with water. However, Cl2 is slightly soluble in water, and it can react to form hypochlorous acid. While its solubility in water is not as high as NH3, it is more soluble than CH4. Therefore, Cl2 is more soluble than CH4 but less soluble than NH3.
4. CO2 (carbon dioxide): Carbon dioxide is a nonpolar molecule, and it does not form hydrogen bonds with water. While CO2 can dissolve in water to a certain extent and react to form carbonic acid, its solubility is relatively low compared to NH3 or Cl2. Therefore, CO2 is expected to be the least soluble among NH3, Cl2, and CO2.
Based on this analysis, the order of solubility from highest to lowest is:
NH3 > Cl2 > CO2 > CH4
