7. Substitution Reactions

Predict the product of the reaction

Predict the product of the reaction

For each reaction, give the expected substitution product, and predict whether the ­mechanism will be predominantly first order (SN1) or second order (SN2).

d. cyclohexylbromide + methanol

e. cyclohexylbromide + sodium ethoxide

Explain why the following alkyl halide does not undergo a substitution reaction, regardless of the base that is used.

Draw the substitution products for each of the following reactions; if the products can exist as stereoisomers, show what stereoisomers are obtained:

c. benzyl chloride + CH₃CH₂OH

d. allyl chloride + CH₃OH

Draw the substitution products for each of the following reactions; if the products can exist as stereoisomers, show what stereoisomers are obtained:

a. (R)-2-bromopentane+CH₃O⁻

b. (R)-3-bromo-3-methylheptane+CH₃OH
