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).

For each compound listed below, predict the dominant mechanism for each reactant (SN1 and/or SN2). The two test reagent mixtures you will be using are sodium iodide in acetone and silver nitrate in ethanol.Note: a compound may not react at all or react under both mechanisms. If both mechanisms are possible, one is usually dominant. Indicate that where applicable.
