Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... i x + P C 1. NaOMe Click and drag to start drawing a structure. 2. H

Predict the major products of this organic reaction. Draw only the major product or products in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If there will be no products because there will be no significant reaction, just check the box under the drawing area and leave it blank. Note for advanced students: you can ignore any products of repeated addition.

Curved arrows are used to illustrate the flow of electrons. Follow the curved arrows and draw the missing reactants/intermediates in this SN1 mechanism.                                               Include all lone pairs. Ignore byproducts. Ignore stereochemistry.

a. First, identify the reactions taking place. Look at the reagents over the arrows. What is the first reaction used for? Does the second reaction use SN1 or SN2 conditions? b. Now look at the big molecule. Based on your answers to B, circle any portion of the molecule you suspect will react under these conditions. Is it a stereocenter? c. Based on your answers to B and C, what will be the stereochemical outcome of this reaction?

Consider the reaction between 2-methyl-2-butanol and HBr, shown below. но HBr Br

Draw an arrow on the carbocation in the box on the left to show how it rearranges to the carbocation in the box on the right.

Provide the missing curved arrow notation and second step for the below E1 mechanism. In the second box, only draw in a byproduct or reagent, such as Br" or CH3OH, if it reacts in that step. Be sure to include lone pair electrons and nonzero formal charges. See Periodic Table See H Provide the missing curved arrow notation for the E1 mechanism. O: I +
