Cinnamaldehyde is an organic compound with the formula C 6 H 5 CH=CHCHO. Cinnamaldehyde occurs naturally in the bark of cinnamon trees of the genus Cinnamomum, Cinnamomum zeylanicum , Cinnamomum cassia , and Cinnamomum camphor . The structural formula of formaldehyde is-There are several uses of formaldehyde and the most notable ones are that it is used in industries, in pharmaceuticals, constructions, food industry, etc. Create your website today. Additional Names: cinnamic aldehyde; phenylacrolein; cinnamal. In this process, LiAlH 4 in excess is added to a solution of cinnamaldehyde, and both functional groups (double bond and carbonyl group) are reduced. 3. This site was designed with the .com. It is shown below: The compound cinnamaldehyde gives the flavor to cinnamon. It is a flavonoid that is naturally synthesized by the shikimate pathway. Identify the class of compound represented by each of the circled functional groups. website builder. Occurring naturally as predominately the trans (E) isomer, it gives cinnamon its flavor and odor. The structural formula for cinnamaldehyde (cinnamon flavor) is shown below. The molecular formula for cinnamaldehyde was determined in 1834 by the French chemists Jean Baptiste André Dumas (1800–1884) and Eugène Melchior Péligot (1811–1890), although its structural formula was deciphered only in 1866 by the German chemist Emil Erlenmeyer (1825–1909). The structural formula of Cinnamaldehyde was determined by Emil Erlenmeyer (1825-1909), a German chemist, in 1866. Therefore, the compound contains an aldehyde group. Structure: Ball and Stick Method Structural Formula And, a common reaction of Cinnamaldehyde is an aldol condensation reaction, which is the first reaction that occurs when Cinnamaldehyde is being synthesized to obtain commercial cinnamon.
