Why are lower members of the aldehyde series, such as methanal and ethanal, completely miscible with water?
Q1. Why are lower members of the aldehyde series, such as methanal and ethanal, completely miscible with water?
Answer: Hydrogen bonding with water
Explanation: Lower aldehydes like formaldehyde are soluble due to hydrogen bonding with water molecules. Solubility decreases as the hydrophobic alkyl chain length increases.
