curved arrows are used to illustrate the flow of electrons. using the provided starting structure, draw the curved electron- pushing arrows for the following reaction or mechanistic steps. be sure to account for all bond-breaking and bond-making steps. then draw any missing organic intermediates or products for this reaction. include all lone pairs in the structures. ignore inorganic byproducts, counterions, and solvents.

Complete the equation for the following proton-transfer reaction by using curved arrows to show the flow of electron pairs and drawing the products of the reaction. • Draw all atoms, including hydrogen atoms. Apply formal charges where appropriate. Assign lone pairs and radical electrons where appropriate. • Use the "starting points" menu to revert to the original molecule(s) shown. • Draw the appropriate electron-flow arrows. • Omit + signs between structures. ● ● H-O: == starting points == ↑ TAYY H T H-C-H H-N-H T H در ?

Curved arrows are used to illustrate the flow of electrons. Follow the arrows and draw the missing intermediates and product formed in this reaction. Include all lone-pairs. Ignore any inorganic byproducts

Ketones and aldehydes are hydrated under acidic or basic conditions. An example of the acid-catalyzed hydration is shown. Complete the first step of this mechanism. Include all lone pairs of electrons, curved arrows, and nonzero formal charges in your mechanism.

Consider the following reactants: H₂O Would substitution take place at a significant rate between these reactants? Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. If you said substitution would take place, draw all the major products in the upper drawing area below. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. If you said substitution would take place, also draw the complete mechanism for one of the major products in the lower drawing area below. If there is more than one major product, you may draw the mechanism for the production of any one of them. Note: be sure you show all the steps in your mechanism. A good check is to make sure the final product of your mechanism is a stable molecule that could be isolated and purified.
