The substances used for the preparation of ether by Williamson's synthesis are: 

Ethyl phenyl ether is treated with conc. $\mathrm{HI}$ at $0°\mathrm{C}$ and the rnixture of products is treated with thionyl chloride. The products formed are

$1-$Phenoxypropane is treated with an excess of concentrated $\mathrm{HI}$ at $0°\mathrm{C}$ and the mixture of products is treated with thionyl chloride. The products formed are:

One mole of $4-$Nitro- catechol ($4-$nitro$-1,2-$Dihydroxybenzene) on treatment with an excess of $\mathrm{NaOH}$ Followed by one mole of methyl iodide gives$-$

Which of the following cannot be prepared by Williamson synthesis?

The sequence of reagents required for the following conversion is

An optically active, pure, four carbon containing saturated alcohol $\mathrm{X}$, when reacted with $\mathrm{NaH}$ followed by ${\mathrm{CH}}_3-\mathrm{I}$ gives a compound $\mathrm{M}$. Same alcohol $\left(\mathrm{X}\right)$ when treated with $\mathrm{TsCl}$ followed by sodium methoxide gives $\mathrm{M}\text{'}. \mathrm{M}$ and $\mathrm{M}\text{'}$ are

Phenyl magnesium bromide reacting with $\mathrm{t}-$Butyl alcohol gives:
