Question

The decreasing order of solubility of methanal (A), propanaldehyde (B), benzaldehyde (C) and acetophenone (D):

• A. $A>B>C>D$
• B. $D>C>B>A$
• C. $D>A>B>C$
• D. $B>A>C>D$

Answer 1

The correct option is A $A>B>C>D$

Solubility decreases due to increase in molecular weight as a result of increase in hydrophobic nature of the alkyl group.
