From the introduction, the reader can detect the contrast between the quotation and the first sentence of the paragraph. Achieving Variety when Introducing Quotations.
(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).
Alkanes are more soluble because they are more like benzene when looking at intermolecular forces. Alcohol on the other hand have OH groups so small carbon chain alcohols are pretty soluble in polar solvents, like water, because they have simliar intermolecular forces.nswers: In the world of solubility the axiom is like dissolves like. In the solvents shown the organic solvents, benzene, chloroform, and dimethyl ether (a gas at room temperature), have relatively polarity constants.
