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.

REACTION RATES The After Thought 1. Cross out the incorrect statement(s) dealing with factors affecting the rate of a chemical reaction. The rate of a chemical reaction increases: - with increasing concentration of a reactant since the number of collisions increases - with decreasing temperature since the activation energy is reduced - by pulverizing a reacting solid because its exposed surface area increases - with the addition of a...
