Did you get this right?

Solution

The correct order of reagents for the following reaction is $[\mathrm{Ag}{({\mathrm{NH}}_{3})}_{2}{]}^{+}{\mathrm{OH}}^{-},{H}^{+}/{\mathrm{CH}}_{3}\mathrm{OH},{\mathrm{CH}}_{3}\mathrm{MgBr}$ & the reaction as well as mechanism is as follows with the correct order of reagents.

The reaction involves ${\mathrm{SN}}_{2}$ mechanism at second step which on further reaction with excess ${\mathrm{CH}}_{3}\mathrm{MgBr}$ to give the final product.
