Question

The rections above involve synthesis or reactions of alcohols and ethers. Identify the mechanism by which they proceed from among the mechanisms listed. Use the letters a - g for your answers.

a = Proton transfer b = Lewis acid/base c = Electrophilic addition

d = E1 Elimination e = E2 Elimination f = SN1 Nucleophilic substitution g = SN2 Nucleophilic substitution

a. )

b.)

c.)

d.)

Answer 1

A) SN2. because rate of reaction depends on HCl as well as epoxide.

B) SN1. since intermediate is carbonation and rate depends only on carbonation.

C) E1. Here also intermediate is carbonation and rate of reaction depends only on carbonation.

D) Lewis acid base.
