Applications. What makes the compound soluble in water in terms of structural feature? Ethylamine when added to water forms intermolecular H−bonds with water.And therefore it is soluble in water.But aniline does not form H−bond with water to a very large extent due to the presence of a large hydrophobic −C6H5group. Stability: Benzaldehyde is stable under common conditions. To Increase Lipid Solubility B. Benzaldehyde(also called Benzenecarbonal) is the simplest representative of the aromatic aldehydes. Depending on the stoichiometry and reaction conditions, these reagents could beused to prepare either benzalacetone or dibenzalacetone. > The solubility of an aldehyde or ketone is a competition between its polar "head" and its nonpolar "tail". Benzaldehyde is obtained by the oxidation of toluene or the hydrolysis of benzylidene chloride, C 6 H 5 CHCl 2. It should be protected from air as it is susceptible to oxidation.
