Explanation:

Cinnamaldehyde is an organic compound with the formula C6H5CH=CHCHO. Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor.[1] It is a phenylpropanoid that is naturally synthesized by the shikimate pathway.[2] This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus Cinnamomum. The essential oil of cinnamon bark is about 90% cinnamaldehyde.[3]

Answer 2

The resonance structure of cinnamaldehyde:

• Cinnamaldehyde is a natural compound with the formula C₆H₅CH = CHCHO.

• It occurs naturally as a trans-isomer, giving cinnamon its flavor and aroma.

• Cinnamaldehyde occurs naturally on the bark of cinnamon trees and other species of Cinnamomum such as camphor and cassia.

• These trees are a natural source of cinnamon, and the essential oil of cinnamon bark is about 90% cinnamaldehyde.

• Cinnamaldehyde is a polar molecule that combines Carbon, Hydrogen and Oxygen.

• The molecular formula is C9H8O.

• In a molecule are two pairs of unallocated electrons connected to oxygen.

• The molecule contains duplicate and one bond.
