- What would the expanded chechanism look like? The 2 ethers at the bottom of the first molecule are throwing me off.Why does the methyl on the right have higher priority than the ethyl on the right when labeling the molecule as an E or Z isomer?2 stereochemistry of brivaracetum, and it is rather interesting to see the methods they use to determine the structure of different isomers. Do you think this likely causes problems when it comes to stereoselectivity of binding sites?
- Why does the additional substituent on the 3rd carbon disappear?The LD50 (“Lethal Dose, 50 %”) is a value used in toxicology which gives the amount of a substance required to kill 50 % of a test population. It is usually reported based on body weight. For racemic carvone LD50 is reported as 1640 mg/kg. 1. Would it consider carvone to be toxic to an average person? Explain. 2. Would it be expected this the LD50 value to be the same for each enantiomer? Explain at the molecular level in stereochemical terms.please label all the important peaks (bonds and functional groups) on the paper by drawing arrows. please explain how you identified each peak. At least 6 peaks have to be labeled and identified.
- Assign the stereochemical configuration (E or Z) for the alkene below. Show your work, indicating clearly which groups are assigned high priority (e.g., through assigning the groups numbers, circling only the high priority groups, or labeling groups as high or low).please provide the machanisms of 1a, 1e, 1fA)Circle all of the stereo centers in MDMA. B) assign the absolute stereochemistry (R or S) for each stereo center
