Consider the structures of the carbocations formed by ortho attack of the electrophile, "NO, on the given starting material. Draw all resonance structures for the carbocation formed by ortho attack of the electrophile NO on the given starting material. If applicable, include the resonance structure in which π bond electrons "move" to the more electronegative atom as a lone pair. Be sure to include all charges and relevant lone pairs. Which resonance structure is the most unstable? Part 1 of 2 :0: NO2 A B :0: :Ö: а NO₂ C NO₂ + Draw all resonance structures for the carbocation formed by ortho attack of the electrophile "NO, on the given starting material. If applicable, include the resonance structure in which I bond electrons "move" to the more electronegative atom as a lone pair. Be sure to include all charges and relevant lone pairs.

Complete the equation for the reaction between the following Lewis acid-base pair. Use curved arrows to show the flow of electrons in the reaction and draw the product. Assign lone pairs and radical electrons where appropriate. Apply formal charges where appropriate. • Draw the appropriate electron-flow arrows. • Use the "starting points" menu to revert to the original molecule(s) shown. • Omit + signs between structures. ● / CH3 1- H₂C-C CH3 H در St ?

Draw the structure(s) of the major organic product(s) of the following reaction. PPhs THF • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If the reaction produces a racemic mixture, draw both stereoisomers. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Include anionic counter-ions, e.g., I, in your answer, but draw them in their own sketcher.

Please do question one, and indicate which resonance form is a greater contributor to the resonance hybrid

What is the missing reactant in this organic reaction? || CH3-C- CH2 -NH2 R No Answer A CH3 CH3-N-CH₂ || C−NH–CH2 C-CH3 + H₂O Specifically, in the drawing area below draw the structure of R. If there is more than one reasonable answer, you can draw any one of them. If there is no reasonable answer, check the No answer box under the drawing area. Note for advanced students: you may assume no products other than those shown above are formed. Click and drag to start drawing a structure. || X :0 Ś

The compound below is treated with chlorine in the presence of light. H₂C CH3 H₂C CH3 Draw the structure for the organic radical species produced by reaction of the compound with a chlorine atom. Assume reaction occurs at the weakest C-H bond. You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. Undo

Question: Draw a mechanism for the following reaction:

Draw the major organic product(s) of the following reactions including stereochemistry when it is appropriate. H20/ H,SO, / HgSO4 CH,CH2-CEC-CH, • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If no reaction occurs, draw the organic starting material. Separate multiple products using the + sign from the drop-down menu.

Organic Functional Groups Identifying positions labeled with Greek letters in acids and derivatives If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ß carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. HO Oneither substituent can be added. OH 0/5 X

Draw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compound below with base. Include all valence lone pairs in your answer. For structures having different hydrogens of comparable acidity, assume that the reaction occurs at the less-substituted carbon. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures using the ↔ symbol.
