the following reactions, draw reasonable mechanisms that describe the chemical transformation that has taken place. To the right, list the name of the elementary mechanistic step used in the transformation.

Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. 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. Br O Substitution will not occur at a significant rate. : CN + X Click and drag to start drawing a structure.

For which reaction mechanisms—SN1, SN2, E1, or E2—of thefollowing statement true? A statement may be true for one or moremechanisms. The mechanism is concerted

2. The following chemical transformations involve multistep mechanisms. Please write a reasonable mechanism for each transformation and label each elementary step.

Show and label the mechanism for the SN1 reaction using the generic chemical species and electron movement. Notice that the reaction does not include a negative charge on the nucleophile.

Write the synthetic step that shows 2-phenyl-2tosylpropane reacting with NaCl to produce 2- chloro-2phenylpropane. Also draw the mechanism for this reaction.
