Consider the following S and your reaction to protect the effect of the changes given below...
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...
1. Given the following structures that react by Sn1, which would react fastest and which would react slowest. Give reasoning. 5-bromo-1,3-pentadiene, bromocyclopentane, (R)-2-bromo-2-methylhexane. 2.If bromocyclohexane reacts faster than chlorocyclohexane in an Sn2 reaction, what could be the reason? 3.You wish to substitute the bromine in the following molecules with a nucleophile. Explain whether the given molecule would react by Sn1 or Sn2 mechanism and explain why. 1-methyl-1-bromo-cyclohexane, 1-bromopropane, 2-bromohexane. 4. Why does benzyl bromide react under both Sn1 and Sn2...
