Rank the following substances in order from most soluble in water to least soluble in water: ethane, C2H6; 1-pentanol, C5H11OH; potassium chloride, KCl; and propane, C3H8. Rank from most to least soluble in water. To rank items as equivalent, overlap them.
Most soluble Least soluble

Explanation:

The substances are:

-) Ethane,

-) 1-pentanol,

-) Potassium chloride,

-) Propane,  

For this question, we have to remember the structure of water. Due to the electronegativity difference between oxygen and hydrogen in this structure, we will have the formation of dipoles. The dipoles interact better with net charges, due to this, the Potassium chloride is the compound with highest solubility (due to the formation of a cation and an anion):

Then, in 1-pentanol we an "OH". This structure due to the presence of the hydroxyl group can form hydrogen bonds. Therefore,  this compound would be the second more soluble.

Finally,  the difference between propane and ethane is a carbon. In propane, we have an additional carbon. If we have more carbons we will have more area of interaction. If we have more area we will have more solubility therefore propane is more soluble than ethanol.

In conclusion, the rank from most soluble to least soluble is:

1) Potassium chloride,

2) 1-pentanol,

3) Propane,  

4) Ethane,

I hope it helps!

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
