1.

What is the product?

a)

an alkene

b)

an ether

c)

a substitution of OH with CH3

d)

formation of a ketone

2.

Mechanistically, the Williamson ether synthesis outlined is:

a)

an E1 process

b)

an SN1 process

c)

an E2 process

d)

an SN2 process

e)

None of the answers are correct

3.

What would be the product?

a)

cyclopentene

b)

cyclopentane

c)

cyclopentanol

d)

methoxycyclopentane

4.

Is there no reaction?

a)

This is false. You get phenol and a halogenated benzene as a product.

b)

True, Diaryl ethers like diphenyl ether are inert under ordinary acidic conditions because the generation of an aryl cation is an SN1 process that is energetically unfavorable, and "back-side" attack at the ring carbon bound to oxygen is sterically unfavorable.

c)

True, Hydrogen halides are not strong enough acids to cleave an ether.

d)

This is false. It yields benzene and phenol.

e)

This is false. It yields 2 phenol compounds

5.

The synthesis of epoxides by base treatment of halohydrins is an example of an intramolecular:

a)

dehydration reaction

b)

hydrolysis reaction

c)

Williamson ether synthesis

d)

SN1 reaction

a)

H3O+

b)

HBr, H2O

c)

Br2

7.

Choose the best reagent for carrying out the following reaction

c)

LiAlH4 in ether, then H3O+

d)

PCC, CH2Cl2

e)

CH3MgBr in ether, then H3O+

8.

Choose the best reagent for carrying out the following reaction

a)

NaOCH3, CH3OH

b)

Hg(O2CCF3)2, CH3OH

c)

11.

Choose the best reagent for carrying out the following reaction

a)

warm H2SO4/H2O

b)

Hg(O2CCF3)2, CH3OH

c)

LiAlH4 in ether, then H3O+

d)

m-ClC6H4CO3H

e)
