1. a. Draw the structures of A and B (resonance structures), and C (tetrahedral intermediate). Us...
1.(10 points) Consider the reactive intermediate below: A) In the space below draw all significantly contributing resonance structures (including lone pairs). Use curved arrows to indicate the flow of electrons between the resonance structures. b) In the resonance structures you have drawn above, predict which one will be the most stabilized resonance contributor. Discuss briefly (1 sentence) why you chose this structure to be the most stable contributor to the resonance hybrid.
EO 3- resonance structures, formal charges, stability 1. Draw ONE possible significant additional resonance structure for each of the following ions. Use curved arrows to show the movement of electrons that creates each new resonance structure. (Hint: lone pairs are not shown. Start by drawing in all one pairs, and include all lone pairs and formal charges in your additional resonance structure.) Page 1 of 3 2. For each structure, draw the resonance structure that is indicated by the curved...
Draw a major resonance structure for the following enolate. Use curved arrows in both structures to show the delocalization of electron pairs. Include lone pairs of electrons, formal charges, and hydrogen atoms. Draw a major resonance structure for the following enolate. Use curved arrows in both structures to show the delocalization of electron pairs. Include lone pairs of electrons, formal charges, and hydrogen atoms.
use curve arrows to indicate election motion and draw resulting resonance structures. rank the resonance structures with respect to their relative contribution to the resonance hybrid. briefly explain your choice. (12 points) Use curved arrows to indicate the electron mation and draw the resultant resonance struct ing from the structure in each case. Remember-It's a good idea to visualize the locations of the H at t aren't shown in the skeletal structures, in order to avoid drawing structures that exceed...
3. Using curved arrows draw all the significant (not negligible) contributing resonance structures for the ions or molecules given below. (curved arrows must show how each proposed structure is generated) a) (5 points) b) (5 points) compond ОН n abom nl ( c) (5 points) 24
(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...
a. Draw the structure of the tetrahedral intermediate INITIALLY FORMED in the reaction shown. b. Draw fhe structures of the final acyl transfer profucts obtained — он + о
4. Three part problem. The structure shown below is stabilized by resonance. H a.) Redraw this structure to the left of the double headed arrow on your answer page. b.) Add one curved arrow to show how the second resonance form could be created. c.) Draw the second resonance form to the right of the double headed arrow. 5. The structure of the previous problem could react with water to form a hydrate. Draw the mechanism of hydrate formation. First,...
1. Please draw all resonance structures (if there are any, not all structures may have resonance structures) for the carbocations A-E (make sure you use resonance arrows (<->). Then circle the carbons that can react with a nucleophile in a SN1-type reaction.
CI + HO CH3 a. Draw the structure of the tetrahedral intermediate INITIALLY FORMED in the reaction shown. b. Draw the structures of the final acyl transfer products obtained.
