Question

Rank the following substances in order from most soluble in water to least soluble in water: methane, CH4; 2-butanol, C4H9OH; potassium chloride, KCl; and propane, C3H8. Rank from most to least soluble in water. To rank items as equivalent, overlap them.

Answer 1

Answer:

Arranged in order of most soluble to least soluble in water:

$KCl > CH_{4} > C_{4} H_{9} OH > C_{3}H_{8}$

Explanation:

Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.

Non-polar molecules would be dissolved by non-polar solvents.

Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
