Question

Best method for preparation of
by williamson's ether synthesis is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Williamson's ether synthesis:
It is used for the preparation of simple as well as mixed ethers.
It involve an alcoholic sodium or potassium alkoxide that reacts with a primary haloalkane to produce ether. Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. They are often written as $R{O}^{–}$, where R is the organic substituent.
$3^o$ alkyl halide react with sodium methoxide and gives alkene not ether because reaction will be elimination not substitution due to presence of strong base sodium methoxide ion $\left(C{H}_3{O}^{-}N{a}^{+}\right).$
