2. In lab, we learned that Br makes a better leaving group than Cl. Do your results (how fast the reaction took place, if a reaction took place, how much participate was produced, etc.) agree with this? Explain. Give specific examples from your results. For the S1 reactions in this lab, what was the identity of the nucleophile? What was the solvent? What are the best types solvents for SN1 reactions. 4. For the S2 reactions in the lab, what...

Since we haven't yet covered this in class, your class textbook may be a valuable source of information in helping to answer these questions. 1. Using the generic chemical species below (E = eletrophile/substrate, LG = leaving group, and Nu nucleophile), show the mechanism (adding curvy arrows/showing electron movement) for both an S, 2 and an S, 1 reaction. Be careful with charges as bonds are broken and created. Also notice that the nucleophile for the S.2 reaction has a...

Part A: Indicate which substrate in each pair is more reactive by an SN2 mechanism and explain why in terms of leaving group ability or substrate degree (primary, secondary, tertiary): 2-chlorobutane and 2-bromobutane 2-chlorobutane and 1-bromobutane 1-chlorobutane and 1-bromobutane 2-bromobutane and 1-bromobutane 2-chloro-2-methylpropane and 2-chlorobutane Part B: Indicate which substrate in each pair (same ones in part a) is more reactive by an SN1 mechanism and explain why in terms of leaving group ability or substrate degree (primary, secondary, tertiary).

1.) What is the order of reactivity of the following reagents under SN1 conditions? Under SN2 conditions? Draw the structures of each using the bond line method and explain your answers. 1-methyl-1-bromocyclohexane, 1-bromopropane, 2-bromohexane 2.) What is the order of reactivity of the following reagents under SN1 conditions? Under SN2 conditions? Explain your answers. CH3CH=CHBr, CH3CH=CHCH2Br, CH3CH2CH2Br 3.) We did not use crotyl chloride in this experiment. However, based on your knowledge of SN1 and SN2 predict the behavior of...

1. You wish to substitute the bromine in the following molecules with a nucleophile. Explain whether the given molecule would react by the Sn1 and Sn2 mechanism and explain why. 1-methyl-1-bromo-cyclohexane, 1-bromopropane, 2-bromohexane. 1.Why does benzyl bromide react under both Sn1 conditions and Sn2 conditions? 2.Why is bromobenzene nonreactive under both Sn1 and Sn2 conditions? 5. If bromocyclohexane reacts faster than chlorocyclohexane in an Sn2 reaction, what could be the reason? 11. Account for the rapid rate of ethanolysis of...
