Explain the solubility of aldehyde and ketone compounds.
(N/A) The lower members of aldehydes and ketones,such as methanal,ethanal,and propanone,are miscible with water in all proportions because they form hydrogen bonds with water molecules.
$(i)$ Intermolecular hydrogen bond between a ketone and a water molecule is shown below:
(ii) Intermolecular hydrogen bond between an aldehyde and a water molecule is shown below:
However,the solubility of aldehydes and ketones decreases rapidly as the length of the alkyl chain increases,due to the increasing hydrophobic character of the hydrocarbon part.
