need help with this part benzene carbocation intermediate DOES NOT Critical Thinking Questions 1. For Rxn 1 (above) draw curved arrows showing the mechanism of electrophilic addition of HCl. Include an appropriate carbocation intermediate in the box above. Figure 1: Reaction Diagrams for Electrophilic Addition of HCI V.E. V.E. (Potential Energy) H-C1 H-C1 carbocation intermediate Reaction Progress (Rxn 2) Reaction Progress (Rxn 1) 2. Rxn 1 is slightly down-hill in terms of energy. Rxn 2 is very up-hill in terms...
Benzene will engage in electrophile aromatic substitution reactions. Which of the following statemtns is NOT TRUE about the mechanism for this reaction? please help I dont know what to put! 3. Benzene will engage in electrophilic aromatic substitution reactions. Which of the following statements is not true about the mechanism for this reaction? A. Formation of a carbocation intermediate is the rate-determining step. B. The carbocation intermediate has an sp3-hybridized carbon in the ring. C. Benzene is an electrophile. D....
Aromatic heterocycles also undergo electrophilic aromatic substitution reactions. When furan is treated with an electrophile, the electrophile is installed only at the C-2 position. Explain why this reaction occurs only at the C-2 position, rather than the C-3 positions.(explain in words and resonance structures) Question 2 (10 pts). Aromatic heterocycles can undergo EAS reactions. When furan (below) is treated with an electrophile, an EAS reaction occurs in which the electrophile is installed only at carbon 2, not carbon 3. Explain...
+ H+ Electrophilic aromatic substitution is a two-step process. In the first step an electrophile, here generically shown as Y , reacts with the aromatic ring to form a resonance-stabilized carbocation intermediate. In the second step, loss of a proton from the site of attack restores aromaticity to the ring and completes the reaction. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions no XT + H H- A
Provide the reaction for chlorination of benzene using electrophilic aromatic substitution, it's complete mechanism including formation of "super" electrophile, and a completely labeled reaction coordinate energy diagram. 1.
organic chemistry 353 2. (4 pts.) Arrange the following in order of increasing electrophilic aromatic substitution reactivity (4 = most reactive): SO3H OH e 3. (4 pts.) Briefly describe why alkenes undergo addition and aromatic compounds undergo substitution. n Briefly describe w 4. (5 pts. Provide an example of an EAS reaction creates an arene that is less reactive than benzene (be specific, include reagents, you do not need to show the mechanism)
For question 2) Electrophiles for the electrophilic aromatic substitution reactions have to be very strong to react with the stable aromatic rings. A nitronium ion is needed for nitration of aromatic rings. Complete the mechanism of the formation of the nitronium ion from concentrated nitric acid in concentrated sulfuric acid. Question 2 of 45 Add curved arrows. Hint Map Complete the structure and add curved arrows to show the formation of the nitronium. Draw the products. Previous Check Answer 0...
