Question

As the carbon chain increases in aldehyde and ketone compounds, solubility in water:

• A. decreases
• B. increases
• C. may increase
• D. may decrease

Answer 1

The correct option is A decreases

As the carbon chain increases in aldehyde and ketone cmpounds, solubility in water decreases.
Thus, aldehydes and ketones with few carbon atoms are water soluble whereas the one having several C atoms are water insoluble. With increase in the number of C atoms, the hydrophobic part of molecule increases. Hence, water solubility decreases. Hence, the correct answer is option (a).
