4. Draw the line-angle structure for each of the following a) (2E,4Z)-4-ethyl-5-isopropyl-3,6-dimethylocta-2,4-diene b) (2Z,4Z,6E)-3-bromo-5-chloro-4-ethyl-7-fluoro-9-methyldeca-2,4,6-triene c) (5S,8S)-3-sec-butyl-5-ethyl-1,8-dimethylcycloocta-1,3,6-triene d) 2-ethyl-3,5,5-trimethylcyclopenta-1,3-diene
Photochemical isomerization of (2E,4E)‑hexa‑2,4‑diene to (2Z,4E)‑hexa‑2,4‑diene is a two‑step process in which a photochemically driven intermediate forms and then thermally rearranges to give the product. Draw the structure of this intermediate, clearly indicating stereochemistry by drawing a wedged bond, a dashed bond and two in‑plane bonds per chiral carbon.The answer is attached below.
