Using the 'like dissolves like' principle, which prediction about solubility is correct?
ANon-polar compounds dissolve well in polar water
BPolar compounds dissolve well in non-polar ether
CAll compounds dissolve equally in any solvent
DPolar compounds dissolve well in polar water
Answer & Solution
Correct answer: D. Polar compounds dissolve well in polar water
1. 'Like dissolves like' means dissolving occurs when solute and solvent are similar in nature.
2. Water is polar, so it dissolves polar compounds such as common salt.
3. Non-polar compounds dissolve in non-polar solvents like ether, not in polar water, ruling out that option.
4. Therefore polar compounds dissolve well in polar water.
