- turbo-Grignard reaction, please tell me the reason for reacting 2-chloropropane first. After that, how will 2-chloropropane eliminate? I would appreciate it if you could tell me about the reaction mechanism.What trend is there in the speed of an SN1 reaction as you change solvent between ethanol,methanol and acetone?In Friedel-Crafts acylation, why is water needed? Why does the entire step 4 mechanism need to occur? Also in the step 4 mechanism, what are the exact arrow-pushing mechanisms for the addition of water?
- why is the temperature cooled to 100degree celcius in the reaction of benzil and 1,3dipenhyl acetone after the addition of the TEG before the adding the base triton B, also what is the mechanisim for that reaction to occur ?why is 12 M HCl added to the reaction mixture after the Williamson Ether Synthesis reaction was complete. (choose all that apply)On a large scale (such as a chemical plant) is it better for the Grignard reagent to attack a hindered carbon or an unhindered carbon? And why?
- Why is it difficult to stop the reaction at the mono-brominated stage?in this reaction, what is compound V?Friedel-Crafts Alkylation, based on substituted benzene reaction, including reactivity based on electron donating and withdrawing group and also discuss the possible positions (Ortho, Meta and Para) for the new group. Explain if there is polysubstitution occurs. Keeping the reaction mixture in the ice bath and adding the reagent slowly by continuously stirring is the key point of success.
