Ethers & Epoxides

Question 1

-If the epoxide has 3° or 1° carbons.
-If there’s NO acidic conditions

Answer 1

-Nucleophile goes to the more subbed carbon under acidic conditions.
-Nucleophile always goes to less subbed carbon

Question 2

Naming ethers:

Answer 2

Name groups attached to Oxygen
2ways to name:
-use -oxy when naming O-R as a functional group
-add -ether at the end

Question 3

Naming epoxides:

Answer 3

-number so that epoxide is 1,2
-add “epoxy” as a functional group

Question 4

Epoxide structure:

Answer 4

O
/_\

Question 5

Ether structure:

Answer 5

R1 — O — R2

Question 6

Williamson Ether Synthesis

-how to know which is preferred?

Answer 6

R-Ø-R = R-OH + R-BR

-Br only wants to be attached to 1           carbon (1°)
