Question

identify the geometrical isomer of stilbene from their alpha max values of 294 and 278 nm​

Answer 1

Explanation:

Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C6H5CH=CHC6H5. Classified as a diarylethene, it features a central ethylene moiety with one phenyl group substituents on each end of the carbon–carbon double bond. It has an (E) stereochemistry, meaning that the phenyl groups are located on opposite sides of the double bond, the opposite of its geometric isomer, cis-stilbene. Trans-stilbene occurs as a white crystalline solid at room temperature and is highly soluble in organic solvents. It can be converted to cis-stilbene photochemically, and further reacted to produce phenanthrene.

Answer 2

Answer:

Trans-stilbene.

Explanation:

Stilbene, generally called trans-stilbene, is represented through the condensed structural system C6H5CH=CHC6H5. Classified as a diarylethene, it capabilities a imperative ethylene moiety with one phenyl organization substituents on every give up of the carbon–carbon double bond. It has an (E) stereochemistry, that means that the phenyl companies are placed on contrary aspects of the double bond, the other of its geometric isomer, cis-stilbene. Trans-stilbene happens as a white crystalline stable at room temperature and is quite soluble in natural solvents. It may be transformed to cis-stilbene photochemically, and similarly reacted to provide phenanthrene.
