Question
Show how you might synthesis the following compounds given the following starting materials. The reactions can be done in one or more steps. do not give the mechanisms. Show reagents and if the reaction takes more than one step show the intermediate product(s) that are made during the synthesis. These reactions are all in your notes. beta-carotene is one of the pigments that cause carrots to look orange. How many nodes would the HOMO of beta-carotene have? beta-carotene is a precursor to vitamin A (Retinal) via the action of an enzyme called beta-carotene-15,15-monooxygenase. How does the energy gap between the HOMO-LUMO of vitamin A compare to beta-carotene. Energy gap between the HOMO-LUMO is larger for beta-carotene Energy gap between the HOMO-LUMO is larger for vitamin A The energy gap would be the same Purified and isolated beta-carotene is actually a red solid and vitamin A is an orange solid. Is vitamin A absorbing a longer or shorter wavelength of electromagnetic radiation? Vitamin A is absorbing at o longer wavelength than beta-carotene Vitamin A is absorbing at a shorter wavelength than beta caroteneExplanation / Answer
6) a) NH2-CH2-CH3
b) CH2=NH
c) NH3
d) BR2 + KOH =KOBR
7) 10 nodes
8) b. energy gap between HOMO LUMO is more in case of Vitamin A
9) Vitamin A is absorbing at a shorter wavelength than beta carotene
