The correct sequence of reagents for the following conversion will be:

$\displaystyle \mathrm{CH}_3 \mathrm{MgBr}, \quad\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+} \mathrm{OH}^{-}$, $\displaystyle \mathrm{H}^{+} / \mathrm{CH}_3 \mathrm{OH}$

$\displaystyle \begin{aligned} & {\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+} \mathrm{OH}^{-}, \quad \mathrm{CH}_3 \mathrm{MgBr},} \\ & \mathrm{H}^{+} / \mathrm{CH}_3 \mathrm{OH} \end{aligned}$

$\displaystyle \begin{aligned} & {\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+} \mathrm{OH}^{-}, \quad \mathrm{H}^{+} / \mathrm{CH}_3 \mathrm{OH},} \\ & \mathrm{CH}_3 \mathrm{MgBr} \end{aligned}$

$\displaystyle \begin{aligned} & \mathrm{CH}_3 \mathrm{MgBr}, \quad \mathrm{H}^{+} / \mathrm{CH}_3 \mathrm{OH}, \\ & {\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+} \mathrm{OH}^{-}} \end{aligned}$
