Options

  1. ACH3MgBr,H+/CH3OH,[ Ag (NH3)2]+OH−{CH}_{3}MgBr, {H}^{+} / {CH}_{3}OH, {\left[\text{ Ag }{\left({NH}_{3}\right)}_{2}\right]}^{+}{OH}^{-}
  2. BCH3MgBr,[Ag(NH3)2]+OH−,H+/CH3OH{CH}_{3}MgBr, {\left[Ag{\left({NH}_{3}\right)}_{2}\right]}^{+}{OH}^{-}, {H}^{+} / {CH}_{3}OH
  3. C[Ag(NH3)2]+OH−,CH3MgBr,H+/CH3OH{\left[Ag{\left({NH}_{3}\right)}_{2}\right]}^{+}{OH}^{-}, {CH}_{3}MgBr, {H}^{+} / {CH}_{3}OH
  4. D[Ag(NH3)2]+OH−,H+/CH3OH,CH3MgBr{\left[Ag{\left({NH}_{3}\right)}_{2}\right]}^{+}{OH}^{-}, {H}^{+} / {CH}_{3}OH, {CH}_{3}MgBr

Correct answer

D. [Ag(NH3)2]+OH−,H+/CH3OH,CH3MgBr{\left[Ag{\left({NH}_{3}\right)}_{2}\right]}^{+}{OH}^{-}, {H}^{+} / {CH}_{3}OH, {CH}_{3}MgBr

Step-by-step solution

The correct order of reagents for the following reaction is [Ag(NH3)2]+OH−,H+/CH3OH,CH3MgBr[ Ag{( {NH}_{3} )}_{2}{]}^{+}{OH}^{-}, {H}^{+} / {CH}_{3}OH, {CH}_{3}MgBr & the reaction as well as mechanism is as follows with the correct order of reagents.

The reaction involves SN2{SN}_{2} mechanism at second step which on further reaction with excess CH3MgBr{CH}_{3}MgBr to give the final product.

The correct sequence of reagents for the following conversion will be
