From Williamson's synthesis preparation of which of the following is possible ?

Options

A. Only symmetrical ethers
B. Only asymmetrical ethers
C. Both `(1)` and `(2)`
D. None of these

Answer

3

Explanation

For synthesis of symmetrical ethers `:`
`CH_(3)O^(ɵ)+BrCH_(3)underset(S_(N)^(2))rarr underset(("dimethyl. ether")
("less stable"))(CH_(3)OCH_(3))+NBr`
For synthesis of asymmetrical ethers `:`
`CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-O^(n)Na^(+)+CH_(3)-Br overset(S_(N)^(2))(rarr)underset("(asymmetrical ether)")underset("methyl ter.butyl either")(CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-O-CH_(3)+NaBr)`
