- According to this video, https://www.youtube.com/watch?v=9Ng6Zv9oLzk, draw the dienophile that was used in the example explaining s-cis and explain what is different about this dienophile from common examples?1 example for organic rearrangement reaction show: a. the overall reaction (reactants --> products) b. the reaction mechanism (indicate intermediate product) c. indicate which is the reactive species or intermediate in the reaction (radical? electrophile? nucleophile?) d. overall description of the reaction eg., radical substitution or SROrgonic Chemistry II: The answer is writtten as followed. But I Need Explanation. My question is that: Can I siwtch reagent 2 to reagent 1? for example reagent 1 is Cl2,Fecl3, can I changed it to reagent 2??? Why and why not???
- Pls ignore the highlighted part __________ is reduced in thefollowing reaction: Cr2O72- + 6S2O32-+ 14H+→ 2Cr3+ + 3S4O62- + 7H2OHELP ASAP! please write out mechanism and reagants/reactants for thisFor 10.29, the trans product (major product) and the cis product (third product) are displayed as possible E2 products. However, for 10.30, only the trans product (major product) is shown. How come the cis product is not needed?
- Why does the final product has the opposite configuration compared to the reactant? Shouldn’t it form OMs first, then OMs gets substituted by Cl- via Sn2 (the 1st inversion of configuration) then the Cl- gets substituted by OCH3- (the 2nd inversion of configuration? To my understanding 2 inversions = same configuration1 example for organic elimination reaction show: a. the overall reaction (reactants --> products) b. the reaction mechanism (indicate intermediate product) c. indicate which is the reactive species or intermediate in the reaction (radical? electrophile? nucleophile?) d. overall description of the reaction eg., radical substitution or SR1 example of reaction for each of the types of organic reactions: substitution, elimination, addition, and rearrangement. Show:a. the overall reaction (reactants --> products)b. the reaction mechanism (indicate intermediate product)c. indicate which is the reactive species or intermediate in the reaction (radical? electrophile? nucleophile?)d. overall description of the reaction eg., radical substitution or SR
