(20) 1. Write mechanisms to account for the following observations. Assume that the sulfur is the...
1. Propose a synthesis for either of the following molecules using the indicated starting materials. You don't have to use all of them, but all your carbon atoms must come from them alone. (Hint: A five membered lactone will spontaneously form from the correct hydroxy acid.) If you provide syntheses for both a 10 pt bonus will be awarded. OH со, КCN Br н Н NO, Br NH2 2. Propose a mechanism to account for the following reaction. Used the...
PLEASE ANSWER ALL A-G, will
give thumbs up!! FOR A, just need explanation why reaction occurs
at C2 position rather than C3, already have mechanism drawn...
PLEASE EXPLAIN OR AT LEAST
JUST ANSWER ALL ASAP, BEFORE TOMORROW!!
10. Furan, an aromatic heterocycle, is capable of undergoing electrophilic aromatic substitution. When furan is treated with an acid chloride in the presence of a Lewis acid, Friedel-Crafts acylation occurs in which the electrophile is installed exclusively at the C2 position. Provide...
Multistep reaction mechanisms Group ActivityTreating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br-Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2ODraw a mechanism for each step. Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.
1-24 need help really lost
Proton Transfer: deprotonation D. 1) Add the appropriate curved arrows for the following deprotonation step. Also add the other product notice how the Tema s can be converted to this by use of a strong base such as sodium a sodium ion (Na) is not drawn, in this case it is just a spectatorio PCW27 - Mechanistic steps - Part Name: Time spent 2) Label the above compounds with the appropriate name from the previous...
How to properly solve these elimination and addition
reactions
Elimination and Addition reactions Purpose: Figuring out the ways that molecules react is the province of the mechanistic chemist. By understanding the mechanisms of reactions, the chemist can manipulate the experimental variables to favor one product over another. This element of control is the province of the synthetic organic chemist. This Workshop continues to explore how we know how molecules react and how this knowledge leads to control of the products....
