(also cinnamic aldehyde, Î²-phenylacrolein), C 6 H 5 CH=CHCHO, a fatty-aromatic unsaturated aldehyde; a colorless liquid with the characteristic odor of cinnamon. It has a boiling point of 252Â°C and a density of 1.110 g/cm 3 (at 20Â°C). It is poorly soluble in water and very soluble in alcohol and ether. Cinnamaldehyde is a component of many essential oils (cinnamon oil and others).
Starch, for example, is not completely insoluble. The main reason for insolubility of polysaccharides, such as cellulose, is the extended intermolecular interactions among polysaccharide molecules.Solubility depends on a solvent's ability to separate solutes into each individual molecule by surrounding it.ugar is soluble in water because it is a polar molecule. water is also a polar molecule... a simple way to remember if a solute will dissolve in a solvent is like dissolves like so polar water will dissolve polar molecules...
