(a) Draw two resonance structures of the cation shown, shifting only one clectron pair in each step. Be sure to include the formal charge on structures B and C. Only move one double bond. Each resonance structure should contain only one charge -a positive charge. (b) Use curved-arrow notation on the given structure A to show its conversion to structure B, and then on structure B to show its conversion to structure C. 1. Draw curved arrows to show conversion of resonance...
Question 3 of 20 (1 pont) X incorrect incorrect × Incorrect X incorrect 2( Incorrect 2e i Incorrect Draw the curved arrow mechanism for the reaction of 2,3-dimethylpentanenitrile and CHjLi, followed by the addition of acid to give the major product in the fewest steps. When given the choice, draw the arrows that lead to resonance structures with full octets around each atom other than hydrogen. Draw all atoms counterions. Reagents needed for each step are provided in the boxes....
Your answer is incorrect. Try again Draw the curved arrow(s) for converting the first resonance structure into the second resonance structure. H,C CHs Edit CH3
(a) Draw two resonance structures of the cation shown below, shifting only one electron pair in each step. Be sure to include the formal charge on structures B and C.(b) Use curved-arrow notation on the given structure A to show its conversion to structure B, and then on structure B to show its conversion to structure C.
Draw the curved arrows and the resulting resonance structure for the following compound. Step 1 In step 1 draw the resonance form that forms a secondary carbocation. Include lone pairs and charges in your structure.
Please help!! 1. a. Draw the structures of A and B (resonance structures), and C (tetrahedral intermediate). Use curved arrows to show how each structure is formed b. Draw the structure of the Nu: you would use to make CompoundD O (tetrahedral intermediate) он c. (i) Explain why H does not react with a pi bond in the ring in Compound Z. (ii) Which resonance structure, A or B, shows why reacting H with the ketone makes the more reactive?...
HOCHE HOB сн. When l-hexene is treated with Bry in water, 1-bromo-2-hexanol is preferentially formed. Draw curved arrows to show the movement of electrons in this step of the reaction mechanism. Arrow.pushing Instructions no 1-XT | HỘH H6 :BINI CH3 :OH CH3 H20-H
Tulung ate n illud aludke place in a single step. In the Sn2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsey's rule whereby the more substituted alkene is generally formed. In E2 elimination,...
During electrophilic aromatic substitution, a resonance-stabilized cation intermediate is formed. Groups, already present on the benzene ring, that direct ortho/para further stabilize this intermediate by participating in the resonance delocalization of the positive charge. Assume that the following group is present on a benzene ring at position 1 and that you are brominating the ring at positon 4. In the box below draw the structure of the resonance contributor that shows this group actively participating in the charge delocalization. -OCH3...
