Does 2-norbornanone react with NaBh4 differently than camphor ? How so? Explain why you get the stereochemical results based on the molecular structures. (you will need to draw the molecules) Please draw the mechanism showing the reaction
Homework Answers
in 2-norbornanone there is no
steric repulsion because there is no bulky group at 7 position that
is why, H- attacks at equitorial position.
In camphor there is steric repulsion because there are two methyl
group present at 7 position that is why, H- attacks at
axial position.

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.

C) D) please
2-bromobutane will react with^-OCH_3 in the present of dimethylsulfoxide, DMSO, as a solvent to create 1-butene and 2-butene by an elimination reaction. Write the chemical equation showing the structural formulas of all reactants and products. How does this mechanism occur? Circle either E1 or E2 Draw the energy diagram for the desired mechanism. Be sure to label activation energies, transition states, energy levels of reactants and products, change of enthalphy, any intermediate (if it exist). Show how...
