How does the water solubility of aldehydes and ketones change as the alkyl chain gets longer?
AIt increases steadily
BIt stays constant
CIt increases, then falls
DIt decreases rapidly
Answer & Solution
Correct answer: D. It decreases rapidly
A longer hydrophobic hydrocarbon part outweighs the polar carbonyl group, so dissolving in water becomes less favourable.
