Williamson's Synthesis

(a) Name the reagents and write the chemical equations for the preparation of the following compounds by Williamson's synthesis : (i) Ethoxybenzene (ii) 2-Methyl-2-methoxpyropane (b)Why do phenols not give the protonation reaction readily?

Define with equation (a ) Riemer - Tiemann Reaction ( b) Williamson's Symthesis

Explain why in the synthesis of ether (B) using (A) or A_(1) all the three standard methods for the perparation of ether (B) fail, i.e., I. Intermolecular dehydration of alcohols II. Alkoxy mercuration-demercuration method III. williamson's synthesis Suggest an alternative method for the preparation of (B) by using (A) or (A_(1)) .

Williamson synthesis is used to prepare

Williamson synthesis is an example of

A : Diphenyl ether is prepared by Williamson synthesis . R : This reaction generally proceed by S_(N)1 mechanism .

Write the reactions of Williamson synthesis of 2-ethoxy-3-methylpentane starting from ethanol and 3-methylpentan-2-ol.

Ethers can be prepared by Williamson synthesis which an alkyl halide is reacted with sodium alkoxide. Di-tert-butyl ether can't be prepared by this method. Explain.
