Preparation of unsymmetrical ethers by William-son's synthesis requires proper choice of the reactants. Comment

Write the names of the reagents and equations for the preparation of the following ethers by Williamson's synthesis : (i) 1- Propoxypropan " " (ii) 2-Methoxy-2-methylpropane " " (iii) Ethoxybenzene " " (iv) Methoxyethane.

Illustrate with examples the limitations of Williamson's synthesis for the preparation of certain types of ethers.

why is it not possible to prepare ditertiary butyl ether by Williamson's synthesis ?

Explain the following with examples : (i) Williamson ether synthesis (ii) Unsymmetrical ethers

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.
