Incorrect
Your answer is wrong. The chemical formula of at least one of your reactants or products is incorrect.
Predict the major products of the following reaction.
Be sure to use wedge and dash bonds to show the stereochemistry of the products when it's important, for example to distinguish between two different major
products.

The irradiation of the E-isomer (shown below) with radiation at 340 nm gives an E:Z ratio of 5:95. Some relevant information for each compound is shown in the table below. Amax 340nm E290 E340 (L mol¹ cm¹) (L mol¹ cm-1) E 340 nm 8000 20000 PE-Z = 0.60 Z 290 nm 16000 2000 Oz-E = 0.30 (a) The reaction proceeds through an excited state. Explain the nature of this excited state, and explain how it allows formation of the E- and Z-isomers. Explain why this isomerisation is unlikely to occur thermally. (b) The product of the equilibrium shown above gives a final ratio with substantially more of one isomer. Explain why this occurs. (c) Explain why the starting concentration of isomers does not affect the final ratio after irradiation.
