Why is 1-Bromobutane faster than Allyl Chloride in a NaI in acetone reaction? It is an SN2 reaction.
1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.
b. Why is...

To test the reactivity of halides in sodium iodide (Sn2). arrange in decreasing reactivity Bromobenzene 1-bromobutane 2-bromo-2-methyl propane Benzyl bromide Allyl bromide 2-bromobutane
2. Why do tertiary alcohols react faster with concentrated hydrochloric acid than do secondary or primary alcohols? 3. Why are rearrangements rare with tertiary alcohols but not with sec- ondary or primary alcohols?
Follow-up Questions 1. The Nal al/acetone test gives a precipitate with 1-chlorobutane and 1-bromobutane, but not l-iodobutane. Why? 2. Why is it important to use a polar solvent such as ethanol in the silver nitrate test? 3. A student decides to repeat the experiment using organochlorides (R-Cl) instead of organobromides. In the Nal test, would organochlorides react faster, slower or at the same rate as the corresponding organobromides? Explain. Would the order of reactivity change? Explain. b. In the AgNO,...
2-chlorobutane 2-bromobutane 1-chlorobutane 1-bromobutane 2-chloro-2-methyl-propane Allyl chloride Benzyl Chloride Bromobenzene Bromocyclohexane Bromocyclopentane 1. Which substrates should be "very reactive" in SN2 reactions? 2. Which substrates should be "very reactive" in SN1 reactions?
Reactivity of Alkyl Halides a. Which test was overall faster? Give a rationale for why that test is faster. Use one of the substrates to help you explain, drawing an energy diagram might help as well. b.For the AgNO3 test: Which substrate was fastest and which was slowest. Why? Draw a mechanism and energy diagram to help you explain these results. Data Table Test Tube # Reaction Time NaI test Reaction Time AgNo3 test 1 2-chlorobutane 00:03.25 No reaction 2...
Why do tertiary alcohols react faster with concentrated HCL than do secondary or primary alcohols? t-butyl alcohol + HCL yields t-butyl chloride This question is in regards to the synthesis of t-butyl chloride experiment
organic chemistry question kinetic study lab 1) justify why benzyl chloride (PhCH2Cl) reacts faster than 2-Chlorobutane under any of the reaction conditions studied. (Sn2 and Sn1) 2) the compounds 2-bromobutane and 2-clorobutane are secondary alkyl halides. what can be concluded with reactions Sn1 (AgNO3 )and Sn2 (NaI)
